Speed, Frequency and Wavelength- Concepts & Calculations

Front

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

Back

Velocity (v) = Frequency (f) × Wavelength (λ)

Front

If a wave has a frequency of 15 Hz and a wavelength of 5 m, what is its velocity?

Back

75 m/s

Front

What happens to the wavelength of a wave as its frequency increases?

Back

The wavelength decreases.

Front

What type of electromagnetic wave is visible to the human eye?

Back

Visible light.

Front

If a wave has a frequency of 2.5 Hz and a wavelength of 20 m, what is its speed?

Back

50 m/s

Front

What is the relationship between frequency and wavelength in waves?

Back

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

Front

Define frequency in the context of waves.

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 successive crests (or troughs) of a wave.

Front

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

Back

Wavelength (λ) = Velocity (v) / Frequency (f)

Front

What is the frequency of a wave with a wavelength of 10 m and a velocity of 30 m/s?

Back

3 Hz
