1.07 x 102 m
6.20 x 106 m
9.60 x 1018 m

PLEASE I WILL AWARD 100 POINTS!!!!

Answer 1

The wavelength of the radio waves is 9.38 x 10^-3 m

Answer 2

The wavelength of the radio waves is
`9.38 * 10^{{3} m`

Step-by-step explanation:

Given:

Frequency= 3.20 x 1010 Hz

Wave speed or speed of light=
`3.00*10^8`

To Find:

Wavelength of radio waves= ?

Solution:

Wavelength of radio waves is mathematically expressed as

`\lambda= (c)/(f)`

where

f = frequency

c= wave speed or speed of light

`\lambda` = wavelength of radio.

So,

`\lambda=(c)/(f)`

`\lambda= (3.00*10^8)/( 3.20 *10^(10))`

`\lambda=0. 938* 10^ {{-2}`

`\lambda= 9.38* 10^ {{-3}`
