Given: 2020 Hz, at 404 m/s, Lambda=................m

To find the wavelength (λ) given the frequency (f) and velocity (v), you can use the formula:

λ = v / f

In this case, the frequency is given as 2020 Hz and the velocity as 404 m/s. Plugging in these values into the formula, we get:

λ = 404 m/s / 2020 Hz

Simplifying, we divide 404 by 2020:

λ = 0.2 m

Therefore, the wavelength (λ) is 0.2 meters.
