Question

a gamma ray is a high energy, high frequency electromagnetic wave that travels at the speed light 3.0 x 10^8 m/s calculate the wavelength of the wave if it's frequency is 10^20hz

Answer 1

Wavelength = (speed) / (frequency)

= (3 x 10⁸ m/s) / (10²⁰ /s)

= 3 x 10⁻¹² meters

That's 3 "nano-millimeters" ... about 0.06 of
the diameter of a single Hydrogen atom ! ! !
