This law states that the angle of reflection and the angle of incidence must be equal.

Amplitude
Properties of Waves
The maximum distance the particles of a medium carrying the wave move away from the rest position. It is a measure of how far the medium moves when disturbed by the wave.

The Law of Reflection
Mechanical Waves
These are waves that require a medium. They travel through a medium but do not carry the medium.
Transverse Waves
These waves move the medium at a right angle to the direction the wave is traveling.
There are a few different types of waves: Mechanical Waves, Longitudinal Waves, Transverse Waves, and Surface Waves.
The number of complete waves that passes a given point in a certain amount of time. Since waves are produced by vibrations, frequency can also be described as the number of vibrations in a given time period. Frequency is measured in Hertz (Hz) named after Heinrich Hertz.

Waves in different mediums travel at different speeds. Speed, wavelength and frequency are mathematically related.
speed=wavelength • frequency
The angle between the reflected wave and a line perpendicular to the medium.

When a wave hits a surface it cannot pass through, it bounces back. This is called reflection. There are two angles that occur when reflection happens.
The angle between the incoming wave and a line perpendicular to the medium.
Occurs when 2 waves combine to make a wave with a larger amplitude. Think of it as waves "helping other waves out."
Constructive Interference
When a wave passes a barrier or moves through a hole in a barrier, it bends and spreads out.
A wave is a disturbance that transfers energy from place to place. The disturbance from a wave is temporary
Waves can travel through solids, liquids, or gases. The material waves travel through is called a medium, although not all waves require one.
Longitudinal Waves:
Longitudinal Waves are waves that move
particles of the medium parallel to the
direction of the wave. They can be compared to moving in a slinky-like form
Mechanical Wave Example
Surface Waves:
These waves are a combination of transverse and longitudinal waves. Surface waves occur at the surface between two mediums, such as air and water.

Reflection
Angle of Incidence
Angle of Reflection
When a wave moves from one medium to another at an angle, it changes the speed as it enters the second medium causing it to bend.
Interference
When two or more waves meet, they have an effect on each other.
Destructive Interference
Occurs when 2 or more waves combine to produce a smaller amplitude wave.
This happens when the crest of one wave and the trough of another wave align.
When a reflected wave and an incoming wave interfere with each other. A standing wave appears to stand in one place. A standing wave is really 2 waves interfering as they pass each other.
Standing Waves (Cont.)
When waves combine to produce an amplitude of zero, the point they balance out is called the node. The crest and the trough is called the antinodes
