It is a form of an EM wave that is propagated perpendicular to the source of energy.

light

can travel in a straight path.

light waves

is when light bounces off an object.

reflection

when a ray of light reflects off a surface, the angle of incidence is equal to the angle of reflection.”

law of reflection

specular reflection, diffuse reflection

is a type of surface reflectance often described as a mirror-like reflection of light from the surface.

specular reflection

the incident light is reflected into a single outgoing direction.

specular reflection

is the reflection of light from a surface such that an incident ray is reflected at many angles, rather than at just one angle as in the case of specular reflection.

diffuse reflection

When light travels from air into water, it slows down, causing it to change direction slightly.

refraction

the change of direction

refraction

when light enters a more dense substance (_______), it 'bends' more towards the normal line

higher refractive index (refraction)

the amount of bending depends on two things:

change in speed, angle of the incident ray

if a substance causes the light to speed up or slow down more, it will refract (bend) more.

change in speed

if the light is entering the substance at a greater angle, the amount of refraction will also be more noticeable.

angle of the incident ray

On the other hand, if the light is entering the new substance from straight on (at 90° to the surface), the light will still slow down, but it won’t change direction at all.

angle of the incident ray

are optical devices that permit the reflection of light.

mirror

demonstrates the law of reflection as it forms the image of the object placed before it.

mirror

a mirror can be

planar, spherical

a spherical mirror can be

convex, concave

makes an image of objects in front of the mirror; these images appear to be behind the plane in which than mirror lies.

plane mirror

A straight line drawn from part of an object to the corresponding part of its image makes a right angle with, and is bisected by, the surface of the ______

plane mirror

real image, virtual image

the rays of light actually meet after reflection.

real image

it appears to meet but not actually meet.

virtual image

It is virtual

plane mirror

It is erect and of the same size as the object

plane mirror

The distance of the object from the ____ is the same as the distance of the image from the ____.

plane mirror

One of the important characteristics of the image is that it is laterally inverted. It means if you raise your left hand it would appear in the ____ that you have raised your right hand.

plane mirror

a method of tracing the path that light takes in order for an individual to view a point on the image of an object.

ray diagram

is the process of making something looks bigger than it is to see object in detail.

magnification

This is the measure of the size of an image compared to the size of the object.

magnification

is the line joining the centers of curvatures of its surface.

principal axis

of a curve is found at a point that is at a distance from the curve equal to the radius of curvature lying on the normal vector.

center of curvature

It is the point at infinity if the curvature is zero.

center of curvature

is a type of spherical mirror in which, the reflecting surface is the inner curved surface of the sphere, i.e. in this type of mirrors the reflecting surface seems to be away from the incident light source.

concave mirror

Because of their shape, the incident light is reflected inwards (converged), thus they are also called converging mirrors and they are used for focusing light.

concave mirror

there is a formation of different images in a

concave mirror

It mainly depends on the distance between the object and the mirror.

concave mirrors

form both real and virtual images.

concave mirrors

is placed very close to the object, a virtual and magnified image is obtained.

concave mirrors

If we increase the distance between the object and the mirror, the size of the image reduces and real images are formed.

concave mirrors

These real images can be projected on a screen.

concave mirrors

The focal point and the center of curvature of the _______ lie in front of the mirror.

concave mirrors

If the cut part of the hollow sphere is painted from inside, then its outer surface becomes the reflecting surface.

convex mirrors

is also known as a diverging mirror as this mirror diverges light when they strike on its reflecting surface.

convex mirror

are always formed with convex mirrors

virtual, erect, diminished images

is a sensory organ that reacts to visible light and allows humans to use visual information for various purposes including seeing things, keeping balance, and maintaining circadian rhythm.

human eye

parts of the human eye

sclera, cornea, pupil, iris, lens, ciliary muscles, vitreous, retina (cones & rods), optic nerve

These are the devices that process light waves to enhance an image for a more clear view.

optical instruments

The use of ______, such as a magnifying lens or any complicated device like a microscope or telescope, usually makes things bigger and helps us see in a more detailed manner.

optical instruments

is a laboratory instrument used to examine objects that are too small to be seen by the naked eye.

microscope

is the science of investigating small objects and structures using a microscope.

microscopy

field glasses

binoculars

are two refracting telescopes mounted side-by-side and aligned to point in the same direction, allowing the viewer to use both eyes (binocular vision) when viewing distant objects.

binoculars

are sized to be held using both hands, although sizes vary widely from opera glasses to large pedestal-mounted military models.

binoculars

is a device used to observe distant objects by their emission, absorption, or reflection of electromagnetic radiation.

telescope

Originally, an optical instrument using lenses, curved mirrors, or a combination of both to observe distant objects.

telescope

now refers to a wide range of instruments capable of detecting different regions of the electromagnetic spectrum, and in some cases other types of detectors.

telescope

2 types of telescope

refracting telescope, reflecting telescope

dioptric telescope

refracting telescope

is a type of optical telescope thatnuses a lens as its objective to form an image (also referred to a dioptric telescope).

refracting telescope

design was originally used innspy-glasses and astronomical telescopes but is also used for long-focus camera lenses.

refracting telescope

is a telescope that uses a single or a combination of curved mirrors that reflect light and form an image.

reflecting telescope

was invented in the 17th century by Isaac Newton as an alternative to the refracting telescope which, at that time, was a design that suffered from severe chromatic aberration.

reflecting telescope

is an optical instrument that uses a system of prisms, lenses or mirrors to reflect images through a tube.

periscope

It consists of a tube with mirrors at each set parallel to each other at a 45-degree angle, with the addition of two simple lenses, and it depends on the occurrence of regular light reflection on the plane mirrors.

periscope

is an instrument for observation

periscope

is an optional instrument that can capture inage either 2D or 3D images.

camera

that allows light to pass through in order to capture an image on a light-sensitive surface (usually a digital sensor or photographic film).

aperture

focus the light entering the camera

lenses

mechanism determines the amount of time the photosensitive surface is exposed to the light.

shutter

can be narrowed or widened.

aperture
