Question

A certain green light has a wavelength of 540 nm (5.4 x 10^-7 m) and travels at 3.0 x 10^8 m/s. What is its frequency?

Answer 1

\[v=f \lambda \rightarrow f=\frac{ v }{ \lambda }=\frac{ 3.0 \times 10^{8} }{ 5.4 \times 10^{-7} }\]

Answer 2

5.56x10^14

Answer 3

Thanks this really helped me a lot
