Relation between focal length and wavelength
WebApr 28, 2024 · Problem 3. Calculate the wavelength of a wave travelling at the speed of 32 m/s and has a frequency of 800 Hz. Solution: We have, V = 32, f = 800. Using the formula we have, V = λ f => 32 = λ (800) => λ = 32/800 => λ = 1/25 => λ = 0.04 m. Problem 4. Calculate the frequency of a wave travelling at the speed of 70 m/s and has a wavelength of ...
