Answer 2

3.00 x 10^8 m/s

Question 3

Period equation

Answer 3

1/frequency

Question 4

Top of a wave

Answer 4

Crest

Question 5

Bottom of a wave

Answer 5

Trough

Question 6

Amplitude

Answer 6

Distance from the 0,0 in a wave to the crest or the trough

Question 7

Wavelength

Answer 7

Distance between the two crests or troughs of a wave

Question 8

Transverse waves

Answer 8

The oscillation is perpendicular to the direction of propagation

Question 9

Longitudinal waves

Answer 9

The oscillation’s parallel to the direction of propagation

Question 10

The six common wave behaviors

Answer 10

Reflection, refraction, dispersion, diffraction, and resonance

Question 11

Reflection

Answer 11

Equal to the angle of incidence, bounces off the surface

Question 12

Refraction

Answer 12

When the wave changes direction because the speed changes

Question 13

Dispersion

Answer 13

The amount that light refracts depends on its wavelength

Question 14

Diffraction

Answer 14

When a wave bends around something

Question 15

Resonance

Answer 15

When the original wave and its reflection line up

Question 16

Regions frequency longest to shortest

Answer 16

AM radio, FM radio, microwaves, infrared, visible ROYGBIV, UV, X-rays, gamma rays
