hi, please can you help on this:
1) whats the frequency of yellow light that has a wavelength 500nm? how long does it take for one wave to be produced?
2) What wavelength is associated with a radio station transmitting at 200MHz?

Contrary to popular belief, we're not going to do your homework for
you. You should be able to do all these problems yourself using just a
frequency (in Hz) x wavelength (in meters) = speed of light (c = 3x108
m/s) OR (f) x (lambda) = (c)
period (T = time for 1 wavelength to move by) = 1 / frequency (in Hz) OR T = 1/f
1 MHz = 1000 Hz
