What is the wavelength of radio waves that have a frequency of 3.20 x 1010 hz? 9.38 x 10−3 m 1.07 x 102 m 6.20 x 106 m 9.60 x 1018 m i will award 100

The wavelength of the radio waves is

Explanation:

Given:

Frequency= 3.20 x 1010 Hz

Wave speed or speed of light=

To Find:

Wavelength of radio waves= ?

Solution:  

Wavelength of radio waves  is mathematically expressed as

where

f = frequency

c= wave speed or speed of light

= wavelength of radio.

So,

i think it is true since you can test the answer and can use observations to complete it.

the answer is na (sodium)
