Homework Statement
The speed of light is [tex]3 \times 10^8 ms^{-1}[/tex]. Calculate the frequency of red light of wavelength [tex]6.5 \times 10^{-7} m[/tex].
Homework Equations
[tex]v = f\lambda[/tex]
[tex]f = \frac{v}{\lambda}[/tex]
The Attempt at a Solution
[tex]v = 3 \times 10^8 \ ms^{-1}[/tex]
[tex]\lambda = 6.5 \times 10^{-7} \ m[/tex]
[tex]f = \frac{3 \times 10^8 }{6.5 \times 10^{-7} }[/tex]
[tex]f = 4.6 \times 10^{14} Hz[/tex]
[tex]f = 450 THz[/tex]
Is my answer correct?
