Unit 4 Waves Review

Front

What is a wave?

Back

A wave is a disturbance that transfers energy through matter or space.

Front

What is wavelength?

Back

Wavelength is the distance between two consecutive crests or troughs in a wave.

Front

What is frequency?

Back

Frequency is the number of wave cycles that pass a point in one second, measured in Hertz (Hz).

Front

What is the relationship between wavelength and frequency?

Back

As wavelength increases, frequency decreases, and vice versa.

Front

What is a compressional wave?

Back

A compressional wave is a type of wave where the medium moves in the same direction as the wave, creating areas of compression and rarefaction.

Front

What is a trough in a wave?

Back

A trough is the lowest point of a wave, opposite to the crest.

Front

What is ultraviolet radiation?

Back

Ultraviolet radiation is a type of electromagnetic radiation with a wavelength shorter than visible light, and it has more energy.

Front

What is reflection in terms of waves?

Back

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

Front

What is refraction?

Back

Refraction is the bending of a wave as it passes from one medium to another due to a change in speed.

Front

What is interference in wave behavior?

Back

Interference is the phenomenon that occurs when two waves meet and combine to form a new wave pattern.
