it forms upright and reduced images

is the light when it passes through one medium to another with different densities, which cause light to change its speed

only radio wave are longer

high energy waves

what color has the highest frequency

what are the two important points to considered to locate the image formed in lenses graphically?

it is thicker in the center than the edges

what are the three most useful rays

the geometric of the lens

highest energy

can cause skin cancer and blindness in humans

it forms real images and virtual images depending on the position of the object

what color has the lowest frequency?

it is also called as diverging lens

can cause cancer

higher energy than light waves

the smooth reflecting surface, usually made up of polished metal or glass, coated with one metallic substance

a points where light rays converge

has enough energy to break chemical bonds in molecules, or remove tightly bound electrons from atoms, which create caharged molecules or atom

it is thicker in the edges and thinner in the center

blocked from eath's surface by atmosphere

used in medicine, industry and astronomy

the portion of the electromagnetic spectrum that human eyes can detect

used in tanning beds and sterilizing equipment

it is also called as converging lens

is a transparent material that made up of glass or plastic that refracts and fucoses

used for communication, medicine and consumer use

higher energy than microwaves but lower than visible light

used in heat lamps
