Question

What is the wavelength of a wave that has a frequency of 6.1⁢ x⁢ 109⁢ ⁢Hz ? c⁢ = λυ where c = 2.998 x 108⁢ m/s

a. 20.4 m
b. 2.04 m
c. 0.49 m
d. 0.049 m

Answer 1

Wavelength = 0.049 m

Step-by-step explanation:

Given that,

The frequency of a wave,
`f=6.1* 10^9\ Hz`

We need to find the wavelength of the wave. We know that,

`c=f\lambda\\\\\lambda=(c)/(f)\\\\\lambda=(2.998 * 10^8)/(6.1* 10^9)\\\\\lambda=0.049\ m`

So, the wavelength of the wave is 0.049 m.
