To find the wavelength of a wave, you can use the formula:
Wavelength (λ) = Speed of propagation (v) / Frequency (f)
Given: Frequency (f) = 200 Hz Speed of propagation (v) = 400 m/s
Using the formula, we can substitute the given values:
Wavelength (λ) = 400 m/s / 200 Hz
Simplifying the expression:
Wavelength (λ) = 2 m
Therefore, the wavelength of the wave with a frequency of 200 Hz and a speed of propagation of 400 m/s is 2 meters.
