waves and wave properties

Front

What is the term for the number of waves that move past one spot in a second?

Back

Frequency

Front

Which part of a wave is known as the trough?

Back

The trough is the lowest point of a wave, represented by letter H in the provided diagram.

Front

What does the letter A represent in a wave diagram?

Back

Wavelength

Front

What is the measurement unit for frequency?

Back

Hertz (Hz)

Front

If a wave has a frequency of 50 Hz and a wavelength of 10 m, what is the speed of the wave?

Back

500 m/s

Front

What is the definition of 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 relationship between wavelength, frequency, and wave speed?

Back

Wave speed = frequency × wavelength.

Front

What is a crest in a wave?

Back

A crest is the highest point of a wave.

Front

How does changing the frequency of a wave affect its wavelength?

Back

Increasing frequency decreases wavelength, and decreasing frequency increases wavelength, assuming wave speed is constant.

Front

What is the formula to calculate wave speed?

Back

Wave speed (v) = frequency (f) × wavelength (λ).
