Most common form of lumiscence in living organism

greatly diffuse the light that recognizing the object on the other side is very difficult if not possible

type of reflection when it occurs when light hits rough or uneven but glossy object

The final effect a radiant energy may have on an object is to be converted to another wavelength. This Conversion is known as?

Xrays example

is the ability of an object to convert one wavelength to another as long as the active energy source is irradiating the object

The colors of most ordinary objects are due to the fact that they do not absorb the same amount of light each wavelength

Light energy has several effects on an object...

When traveling in open space, light travels in straight line. However, when light comes in contact with an object, it may be bended

The object not only converts the wavelength while being irradiated but continuous to reflect the new wavelengthsfor a period of time after the energy source is removed.

Those with shorter pr longer wavelengths are commonly referred as

Infrared rays examples

Defined as the bending of light around the corners of an obstacles or aperture into the region of geometrical shadow of the obstacle

have a wavelength ranges from 1,000 up nanometer

type of reflection; it happens when light hits a flat, smooth and shiny surface

Blue milli-microns

Color may arise from differences in the refractive or bending power of a transparent medium of light of different wavelength. (ex rainbow)

is a form of art . has elements that might not be the first thing that we think about when we take a photograph

from 30-400 nanometers

is the distance from the crest to the wave to the next succeeding crest

When all the wavelengths between 400-700 nanometers are presented to the eye in nearly equal quantity, we get the sensation or perception of colorless or...

absence of all colors

the product of wavelength and frequency is

Is the generation of light by chemical reaction

3 secondary colors of light

from 400-700 nanometers

Ultra Violet examples

Classification of Daylight According to its Intensity

is the number of waves passing in a given point in one second

Red milli-microns

refers to the color itself

Is the movement of light from one medium into another medium

Bending of Light

Process by which the energy absorbed by the substance is released relatively slowly in the form of light

stimulated to the substance by the absorption of incident radiation and persisting only as long as the stimulating radiation is continued

This any color perception has three characteristics, any one which can be varied independently of the othe two.

is one of a number of known forms od radiant electromagnetic energy which travel in wave motion

The light reflected from the rop surface of such a film undergoes a reversal or phase but the light reflected from the bottom surface does not undergo this type of change

It can cause bending of the ligh at the interfere between media

the presence of all colors

from .01 to 30 nanometers

The objects on the other aide may be recognized but the sharp detail and outline are obscurred

This happens when molecules of the fluorescent material absorb enrgy at one wavelength and radiate it at another wavelength

Categories of Luminescence

Green milli-microns

Allows sufficient visible light to pass through them that the object on the other side may be clearly seen

3 primary colors of light

light bounces off an object when flat surface , smooth, shiny reflect at the same time

Is a radiant electromagnetic energy that can be seen by the naked eye

Types of Reflection

Kinds of object as to how they behave to light

Is a radiant electromagnetic energy that can be seen by the naked eye

Light rays with a wavelength of 400-700 nanometer is referred to as

from 700-1000 nanometers

Variation in the density of the atmospheric gases act in such a way that they scatter light of the shorter wavelength at the blue end of the spectrum much more they scatter light of the longer wavelength of the red end of the spectrum

Those with shorter or longer wavelengths are commonly referred as?

Allows light to pass, however diffuse it sufficiently that objects on the other side may not be clearly distinguished

Is a general term for the emission of light from a cool object.

Production of Colors

Refers to various phenomenon that occur when a wave encounters an obstacle or a slit.
