Waves

Front

What is reflection in the context of waves?

Back

Reflection is the bouncing back of a wave when it hits a barrier or a surface.

Front

What is refraction?

Back

Refraction is the bending of waves as they pass from one medium to another due to a change in speed.

Front

Define scattering in wave behavior.

Back

Scattering is the process by which waves are forced to deviate from a straight trajectory due to non-uniformities in the medium.

Front

What is absorption in wave behavior?

Back

Absorption is the process by which a wave's energy is taken up by the medium, converting it into other forms of energy.

Front

What is constructive interference?

Back

Constructive interference occurs when two waves meet and combine to form a wave of greater amplitude.

Front

What is destructive interference?

Back

Destructive interference occurs when two waves meet and combine to form a wave of lesser amplitude.

Front

What is wavelength?

Back

Wavelength is the distance between successive crests or troughs of a wave.

Front

What is amplitude?

Back

Amplitude is the maximum extent of a wave's displacement from its rest position.

Front

Define crest in wave terminology.

Back

A crest is the highest point of a wave.

Front

Define trough in wave terminology.

Back

A trough is the lowest point of a wave.
