Question

A radio wave with a wavelength of 4.9×10^-1 m is detected by radio telescope what is the frequency of a wave?

Answer 1

6.1184 * 10^8

Step-by-step explanation:

To find the frequency of the radio wave using wavelength, we can use the formula

c = λ v

where

c = 2.998 * 10 ^ 8 (speed of light)

λ = 4.9 * 10^-1

v = frequency

Thus, we have

2.998 * 10 ^ 8 = 4.9 * 10^-1 v

v = 6.1184 * 10^8
