What is the wavelength for radio waves with frequency 3 × 109?
1 × 10–1 m
3 × 10–1 m
3 × 1017 m
9 × 1017 m

Answer 1

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
