## Homework Statement

Angular Speed of the 8 gap wheel Is variable.

Red Laser (wavelength around 656.6 nm)

Approximate the length of the traveling ray to the mirror in meters.

Using the length of the traveling ray, calculate the speed of light.

## Homework Equations

c=lambda*f

## The Attempt at a Solution

I tried using a simple speed * time * distance equation but it didn't make sense to me.

I have looked for other similar threads but they are all dealing with different variables like finding out the perfect timing ect.
