Step-by-step explanation:
Given What is the wavelength for radio waves with frequency 3 × 109?
- We need to find the wavelength with frequency 3 x 10^9
- We have c = f λ
- Here c is speed of light = 3 x 10^8 m/s, f = 3 x 10^9
- So substituting the given values we get
- 3 x 10^8 = 3 x 10^9 x λ
- Or λ = c/f
- = 3 x 10^8 / 3 x 10^9
- Or λ = 1 x 10^- 1 m
- So the wavelength for radio waves with frequency 3 x 10^9 is 1 x 10^-1 m
