Question

What is the frequency of an electromagnetic wave with a wavelength of 1.0 x 10 m?

Answer 1

Answer: 0.03 Hz

Step-by-step explanation:

The frequency
`f` of a light with a wavelength
`\lambda=1(10)^(10) m` is calculated by the following equation:

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

Where
`c=3(10)^(8)m/s` is the speed of light

Then:

`f=(3(10)^(8)m/s)/(1(10)^(10) m)`

`f=0.03 s^(-1)=0.03 Hz` This is the frequency
