Answer to Question #2294 in Mechanics | Relativity for melany

Question

Two waves travel in the same medium at the same speed. One wave has frequency 5.72×105 Hz and wavelength 0.533 m. The other wave has frequency 6.13×105 Hz. What is the second wave's wavelength? answer in meters.

Answer 1

We use the following expression for the velocity of the wave v = λf
λ₁f₁ = λ₂f₂.
0.533*5.72×105= 6.13×105*λ₂,
λ₂ = 0.497 m.
