Waves Review

Front

What is the formula to calculate the time period of a wave?

Back

Time period (T) = 1 / Frequency (f)

Front

If the frequency of a wave is 10 Hz, what is its time period?

Back

0.1 s

Front

What is the definition of frequency in the context of waves?

Back

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

Front

How do you calculate the frequency of a wave if you know the distance between crests and the time taken?

Back

Frequency (f) = Number of crests / Time taken.

Front

What type of interference occurs when two waves combine to form a larger wave?

Back

Constructive Interference.

Front

What type of interference do noise cancelling headphones use?

Back

Destructive Interference.

Front

What is the definition of amplitude in wave physics?

Back

Amplitude is the maximum displacement of points on a wave from its rest position.

Front

If two waves with amplitudes of 3 m interfere, what is the amplitude of the resulting standing wave?

Back

6 m.

Front

What is reflection in the context of waves?

Back

Reflection is when a wave bounces off an object.

Front

What is refraction in wave physics?

Back

Refraction is the bending of waves as they pass from one medium to another.
