Kinds of Waves
A wave that consists of electric and magnetic fields that vibrate at right angles.
Electromagnetic wave
The bouncing back of a ray of light
reflection
A combination of waves that result in a single wave
interference
These are substances that give another substance color.
pigment
an electromagnetic wave of a frequency between about 10 and 10 or 10 Hz, as used for long-distance communication.
radio wave
The bending of a ray of light
refraction
the passing of light or other forms of energy through matter
transmission
The spectrum that consists of all possible forms of radiation.
Electromagnetic spectrum
penetrating electromagnetic radiation of a kind arising from the radioactive decay of atomic nuclei.
Gamma wave/ray
Transfer of light energy to/through matter
absorption
Name all (3) IN ORDER: You can't see through it, you can kind of see through it, you can see through it.

Speed of light
an electromagnetic wave with a wavelength in the range 0.001–0.3 m, shorter than that of a normal radio wave but longer than those of infrared radiation.
Microwave
an interaction of light with matter that causes light to change its energy, direction and motion
scattering
Seeing color is a result of what kind of interaction of light?
reflection
The transfer of energy as electromagnetic waves is known as?
radiation
portion of the electromagnetic spectrum extending from the violet, or short-wavelength, end of the visible light range to the X-ray region.
Ultraviolet
A change in direction of a wave when it encounters an obstacle.
diffraction
What color is produced in the absence of green light?
Purple
