Question

Calcaulate the wave number and frequency of rediation having wave lenght 4800 armstrong

Answer 1

Answer:

Frequency divided by the speed of light is ν/c, which from the above equation is 1/λ. When wavelength is measured in metres, 1/λ represents the number of waves of the wave train to be found in a length of one metre or, if measured in centimetres, the number in one centimetre.
