Homework Statement
The speed of light in a vacuum is 3.00x(10*8)m/s. Using the equation v=fxλ, calculate the frequency of red-light. (I was told to use the wavelengths given from textbook)
Wavelength/λ =700nm
v=300,000,000 <-- ( I need help understanding this. Is this a rate? Or?)
Homework Equations
700nm = 0.00000070 meters.
^ This is what I'm confused on, do i convert this then plug it into the equation or? I'm also confused on how to plug it in.
The Attempt at a Solution
v= 3x(10*8)=300,000,000
f= 300,000,000/0.00000070=4.2857143*14 <-- I understand this is the wrong answer, however I'm terribly confused as to how to find the correct one. Even looking at examples, I don't understand what's converted and how to go about answering it.
Thank you.
