Question

Sunlight is composed of wavelengths of light that make up part of the electromagnetic spectrum. Towson University Exam Question. The frequency of a wave is directly proportional to the speed at which the wave is traveling. Do NOT Copy! Calculate the frequency (in Hz) of light at the following wavelength:

Answer 1

`f= 5.11 * 10^(10)Hz`

Step-by-step explanation:

Given

`\lambda = 0.587cm`

Calculate the frequency

Frequency is calculated using:

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

Where

`c \to` speed of light

`c =299792458 ms^(-1)`

`\lambda = 0.587cm`

Convert wave length to meters

`\lambda = 0.587 * 0.01m`

`\lambda = 0.00587m`

So, we have:

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

`f=(299792458 ms^(-1))/(0.00587m)`

`f=(299792458)/(0.00587)Hz`

`f= 5.11 * 10^(10)Hz`
