the speed of sound in air is 330ms^-1 , speed of light is 3 x10^8 ms^-1... what's the frequency of radio waves of wavelength 100mm ?

How are speed, wavelength, and frequency related?
 


wave speed = frequency * wavelength
 


poojarao said:
wave speed = frequency * wavelength
Good. That's all you need to solve for the frequency.
 


ya but which speed do i use?

Both light and radio waves are examples of electromagnetic waves, which have the same speed in a vacuum.
