Question

Estimate the ratio of shortest wave length of radio waves to the longest wave length of gamma waves.

Answer 1

Radio waves:

Shortest wavelength `(lambda_("radio", "min"))` ≈ 1 mm = 10⁻³ m

Gamma rays:

Longest wavelength `(lambda_("gamma", "max"))` ≈ 10⁻¹⁰ m

Ratio = `(lambda_("radio", "min"))/(lambda_("gamma", "max"))`

= `(10^-3 m)/(10^-10 m)`

= 10⁷
