the smooth reflecting surface, usually made up of polished metal or glass, coated with one metallic substance mirror
is the light when it passes through one medium to another with different densities, which cause light to change its speedrefraction
is a transparent material that made up of glass or plastic that refracts and fucoseslens
it is thicker in the center than the edgesconvex lens
it is thicker in the edges and thinner in the centerconcave lens
it is also called as converging lensconvex lens
it is also called as diverging lensconcave lens
it forms real images and virtual images depending on the position of the objectconvex lens
it forms upright and reduced imagesconcave lens
what are the two important points to considered to locate the image formed in lenses graphically?vertex and focal point

used for communication, medicine and consumer usemicrowaves
higher energy than microwaves but lower than visible lightinfrared waves
used in heat lampsinfrared waves
only radio wave are longer microwaves
the portion of the electromagnetic spectrum that human eyes can detectvisible light
what color has the lowest frequency?red
what color has the highest frequency violet
higher energy than light waves ultraviolet waves
can cause skin cancer and blindness in humansultraviolet waves
used in tanning beds and sterilizing equipment ultraviolet waves
used in medicine, industry and astronomy x-ray
blocked from eath's surface by atmosphere gamma rays
has enough energy to break chemical bonds in molecules, or remove tightly bound electrons from atoms, which create caharged molecules or atomionizing radiation
