Speed, Frequency and Wavelength- Concepts & Calculations

Front

What type of light is the only type of EM wave detected by the human eye?

Back

Visible light.

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

Which region of the electromagnetic spectrum has the lowest frequency?

Back

Infrared.

Front

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

Back

As frequency increases, wavelength decreases, and vice versa.

Front

If a wave has a velocity of 25 m/s and a frequency of 12.5 Hz, what is its wavelength?

Back

2 m.

Front

What is the speed of a wave with a frequency of 10 Hz and a wavelength of 4 m?

Back

40 m/s.

Front

Define wavelength in the context of waves.

Back

Wavelength is the distance between successive crests of a wave.

Front

What is 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

How do you convert frequency to period?

Back

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