Light/Electromagnetic wave 

Electromagnetic energy

Crest

Highest part of a wave

Trough

Lowest part of a wave

Wavelength

the length of a wave

Amplitude

how high the wave is

Frequency

frequency of a wave

Visible light

red, orange, yellow, green, blue, indigo, and violet

Prism

a solid geometric figure whose two end faces are similar, equal, and parallel rectilinear figures, and whose sides are parallelograms.

Spectroscope

Medium

in the middle

Reflection

casting back a light or heat, mirroring, or giving back or showing an image

Refraction

the bending of light or sound as it passes through something like a wall (sound) or a window (light)

angle of reflection

angle made by a reflected ray

angle of refraction

the angle between a refracted ray and the normal drawn at the point of incidence to the interface at which refraction occurs

Law of reflection

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

total internal reflection

complete reflection of a ray of light within a medium such as water or glass from the surrounding surfaces back into the medium
