Answer :
The wavelength of the radio wave is 100.499995 kilometers longer than the wavelength of the gamma ray.
To find the difference in their wavelengths, subtract the wavelength of the gamma ray from the wavelength of the radio wave:
Difference = Wavelength of radio wave - Wavelength of gamma ray
= 100.5 km - 0.000005 km
= 100.499995 km
