What is the frequency of electromagnetic radiation having a wavelength of 2.26 ✕ 10-8 m? s-1 What type of electromagnetic radiation is this?

Question

What is the frequency of electromagnetic radiation having a wavelength of 2.26 ✕ 10^-8 m? 

 s^-1 What type of electromagnetic radiation is this?

Answer 1

The relationship you need is c = λν where c is the speed of light (3.0 ^m/_s, a constant), λ is wavelength, and ν (Greek letter "nu") is frequency (s^–1 or Hz). Given either variable, you can solve for the other.

Given λ = 2.26 x 10^–8 m

Asked ν = ?

c = λν can be rearranged by dividing both sides by λ; c/λ = ν

So, ν = c/λ, substitute the values for c and λ; ν = (3.0 x 10^{8 m}/_s) / (2.26 x 10^–8 m)

Do the math to find the value for ν (in s^–1)

Look for an image of the electromagnetic (EM) radiation which shows the frequency or wavelength scale to determine the type of EM radiation to which this frequency and wavelength correspond.
