Answer to Question #2295 in Mechanics | Relativity for krissy
Two waves travel in the same medium at the same speed. One has wavelength 0.0382 m and frequency 9.67×106 Hz. The other has wavelength 0.0481 m. What is the period of the second wave? answer in seconds.
If the speed of waves is the same for each of it, λ1f1 = λ2f2. 0.0382*9.67×106 = 0.0481*f2, f2 = 7.68×106 Hz.
