Waves test review

Front

What happens to the pitch of a siren as a police car passes by?

Back

The pitch decreases due to the Doppler effect.

Front

What happens to the wavelength when the frequency of a wave increases?

Back

The wavelength decreases.

Front

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

Back

Frequency is the number of complete waves passing a fixed point in a given amount of time.

Front

What type of wave is characterized by particle motion parallel to the direction of wave propagation?

Back

Longitudinal wave.

Front

If the period of a pendulum is 10 seconds, what is its frequency?

Back

0.1 Hz.

Front

What is the relationship between frequency and wavelength in waves?

Back

As frequency increases, wavelength decreases, and vice versa.

Front

Define amplitude in the context of waves.

Back

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

Front

What is the formula to calculate the frequency of a wave?

Back

Frequency (f) = 1 / Period (T).

Front

What is a transverse wave?

Back

A wave in which the particle displacement is perpendicular to the direction of wave propagation.

Front

What is the speed of a wave if its frequency is 5 Hz and its wavelength is 2 meters?

Back

Speed = Frequency x Wavelength = 5 Hz x 2 m = 10 m/s.
