Question

A certain fm radio wave has a frequency of 1.31*10^8 he given that radio waves travel at 2.99*10^8 m/s what is the wavelength of this fm radio wave

Answer 1

The answer is "
`3.92 * 10^(16) \ m`"

Step-by-step explanation:

Given:

`\to v= 1.31 * 10^8 \\\\\\to f=2.99* 10^8 \ (m)/(s)\\\\`

Using formula:

`\lambda=vf\\\\`

`=2.99* 10^8 * 1.31* 10^8\\\\=2.99* 1.31* 10^(16)\\\\=3.9169 * 10^(16) \ m`

`=3.92 * 10^(16) \ m`
