The wavelength of the sound produced by a tuning fork of frequency 450...
Given:
Frequency of tuning fork (f) = 450 Hz
Velocity of sound in air (v) = 320 m/s

To find:
Wavelength of sound produced by the tuning fork

Formula:
Wavelength (λ) = v/f

Calculation:
Substituting the given values in the formula, we get:
λ = v/f
λ = 320/450
λ = 0.711 m

Therefore, the wavelength of the sound produced by the tuning fork of frequency 450 Hz in air is 0.711 m.
