Waves

Front

What is a wave?

Back

A wave is a disturbance that transfers energy from one place to another without transferring matter.

Front

What is frequency?

Back

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

Front

What is wavelength?

Back

Wavelength is the distance between two consecutive points of a wave that are in phase, such as crest to crest or trough to trough.

Front

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

Back

The speed of a wave (v) can be calculated using the formula: v = frequency (f) × wavelength (λ).

Front

If a wave has a frequency of 5 Hz and a speed of 25 m/s, what is the wavelength?

Back

5 m

Front

If the speed of a wave is 74 m/s and the wavelength is 12 m, what is the frequency?

Back

6.2 Hz

Front

Which letter represents wavelength in a wave diagram?

Back

A (assuming A is marked as the wavelength in the diagram).

Front

If the frequency of a wave is 3.3 Hz and the wavelength is 7.4 m, how fast is the wave moving?

Back

24.4 m/s

Front

A guitar string vibrates with a frequency of 320 Hz. If the wavelength of the vibration is 0.23 meters, what is the speed of the wave?

Back

73.6 m/s

Front

What is the relationship between frequency and wavelength?

Back

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