Wave Equation

Front

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

Back

Speed = Wavelength × Frequency

Front

If a wave has a frequency of 60 Hz and a wavelength of 2 m, what is its speed?

Back

120 m/s

Front

Define wavelength in the context of wave motion.

Back

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

Front

What is the relationship between frequency and wavelength in wave motion?

Back

Frequency and wavelength are inversely related; as frequency increases, wavelength decreases.

Front

What is the term for the highest point of a wave?

Back

Crest

Front

How do you calculate the frequency of a wave if you know its speed and wavelength?

Back

Frequency = Speed / Wavelength

Front

What is the unit of frequency?

Back

Hertz (Hz)

Front

What is the lowest point of a wave called?

Back

Trough

Front

If a wave travels at a speed of 300 m/s and has a frequency of 150 Hz, what is its wavelength?

Back

2 m

Front

What happens to the speed of a wave if the medium through which it travels changes?

Back

The speed of a wave can change depending on the properties of the medium.
