Answer to Question #2294 in Mechanics | Relativity for melany
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.
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.
