 A ray that is bended.
Term
 Angle of Incidence
Definition
 The initial Angle.
Term
 Angle of Refraction
Definition
 The angle that causes the bending of the ray.

Term
 Amplitude
Definition
 The measurement from the base of the wave to the crest.
Term
 Wavelength
Definition
 The distance from one crest to the next.
Term
 Period
Definition
 It is the frequency of the wave.
Term
 Frequency
Definition
 The amount of waves in a certain amount of time.
Term
 Crest
Definition
 The top of a wave.
Term
 Trough
Definition
 The lowest point of a wave.
Term
 Compression
Definition
 It causes the wave to have a higher frequency.
Term
 Rarefaction
Definition
 It causes the wave to have a lower frequency.
Term
 Destructive Interference
Definition
 It causes the wave to brake.
Term
 Constructive Interference
Definition
 It causes the wave to become bigger.

 Double-slit Interference
Definition
 A double obstacle the wave encounters.
Term
 Wave Speed
Definition
 The speed of the wave per the amount of time.
Term
 Longitudinal Wave
Definition
 A wave that goes in the same direction as the force source.
Term
 Transverse Wave
Definition
 A wave that goes perpendicular to the power source.
Term
 Snell's Law
Definition
 The law of refraction which states that the waves bend.
Term
