Homework Equations
[tex]v = f \lambda[/tex]
The Attempt at a Solution
PART A
[tex]f = \frac{v}{\lambda} = \frac{3*10^8}{450*10^{-9}} = 4.62*10^{14} Hz[/tex]
*CORRECT*
PART B
[tex]f = \frac{v}{\lambda} = \frac{3*10^8}{650*10^{-9}} = 6.67*10^{14} Hz[/tex]
*CORRECT*
PART C
Not sure. Can someone point me in the right direction?
