The formula for calculating velocity of wave is expressed as
v = fλ
where
v = velocity of the wave
λ = wavelength
f = frequency of the wave
From the information given,
v = 340
f = 502
Substituting these values into the formula, we have
340 = 502λ
Dividing both sides of the equation by 502,
340/502 = 502λ/502
λ = 0.68 m
The wavelength is 0.68 m
