Question

A green laser pointer emits light with a wavelength of 536 nm. What is the frequency of this light?

Answer 1

Answer:

Your answer is 5.63 × 10^14 Hz

We know the value of the speed of light and we are given the wavelength. All we have to do is rearrange the equation to solve for the frequency:

frequency: v = c/ λ

Now just plug in the given values:

v = 3.00 × 10 ^ 8 / 530 × 10^-9

v = 5.66 × 10 ^ 14 Hz

I hope this helps you.
