Question

Radio waves travel at the speed of light:3 x 10^5 km/s.What is the wavelength of radio waves received at 92.5 MHz on your FM radio dial?Answer in units of m.

Answer 1

v=h*f

`\begin{gathered} v=\lambda\cdot f \\ (v)/(f)=\lambda \\ \lambda=(3\cdot10^8m/s)/(92.5\cdot10^6Hz)=3.24m \end{gathered}`

FM is between
