Which one of the following frequencies of radiation (in \(\mathrm{Hz}\) ) has a wavelength of \(600 \mathrm{~nm} ?\)
- A \(2.0 \times 10^{13}\)
- B \(5.0 \times 10^{16}\)
- C \(2.0 \times 10^{14}\)
- D \(5.0 \times 10^{14}\)
Answer & Solution
Correct Answer
(D) \(5.0 \times 10^{14}\)
Step-by-step Solution
Detailed explanation
\(\begin{aligned} v & =\frac{c}{\lambda} \\ & =\frac{3 \times 10^8}{600 \times 10^{-9}} \\ v & =5 \times 10^{14} \mathrm{~Hz}\end{aligned}\)
