Question
Longitudinal wave is produced on a slinky. The frequency of the wave pulse is 60Hz and it travels with a speed of 30 cm/s. The separation between two consecutive compressions is-
Solution
To find the separation between two consecutive compressions, which is also known as the wavelength, we can use the formula for wave speed:
v = f * λ
where: v = wave speed f = frequency λ = wavelength
We know the wave speed (v) is 30 cm/s and the frequency (f) is 60 Hz. We can rearrange the formula to solve for the wavelength (λ):
λ = v / f
Substituting the given values:
λ = 30 cm/s / 60 Hz = 0.5 cm
So, the separation between two consecutive compressions is 0.5 cm.
