Question

What is the frequency of a wave with a wavelength of 3.20 x 10^10 Hz

Answer 1

3.20 x 10^10 = 32,000,000,000 = 1E-08

Explanation:

f = C/λ

Where,

λ (Lambda) = Wavelength in meters

c = Speed of Light (299,792,458 m/s)

f = Frequency (MHz)

Answer 2

Frequency,
`f=9.37* 10^(-3)\ Hz`

Explanation:

Given that : The wavelength of the wave,
`\lambda=3.2* 10^(10)\ m`

To find : Frequency of a wave

Formula used :
`f=(c)/(\lambda)`

Where c is the speed of light

We know that the relationship between the frequency, wavelength and the speed of light is given by :

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

`f=(3* 10^8\ m/s)/(3.2* 10^(10)\ m)`

f = 0.009375 Hz

or

`f=9.37* 10^(-3)\ Hz`

So, the frequency of a wave is
`9.37* 10^(-3)\ Hz`. Hence, this is the required solution.
