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 ?
The discussion revolves around calculating the frequency of radio waves given a wavelength of 100mm. The subject area includes wave properties and the relationship between speed, wavelength, and frequency.
The discussion is active, with participants questioning the appropriate speed to use in the calculation. Some guidance has been provided regarding the relationship between wave speed, frequency, and wavelength.
There is a distinction being made between the speed of sound and the speed of light, with participants noting that electromagnetic waves travel at the speed of light in a vacuum.
Good. That's all you need to solve for the frequency.poojarao said:wave speed = frequency * wavelength
Both light and radio waves are examples of electromagnetic waves, which have the same speed in a vacuum.poojarao said:ya but which speed do i use?
