Calculate the wavelength λ1 for gamma rays of frequency f1 = 7.50×1021 hz .
THIS IS THE BEST ANSWER 👇
Gamma rays are in the class of electromagnetic waves and therefore have the same speed equal to the speed of light, that is, 3×10 ^ m / s
Wavelength = speed / frequency = (3×10 ^ 8) / (7.50×10 ^ 21) = 4×10 ^ -14 m
