Answer 1

Question 5520

What is the frequency of a wave if its wavelength is $3.6 \times 10^{-9} \, \mathrm{m}$ and its velocity is $3.0 \times 10^{-8} \, \mathrm{m/s}$?

Please explain your answer

The wavelength is by definition: $\lambda = \nu T = \frac{\nu}{\nu}$ Hence, the frequency is $\nu = \frac{\nu}{\lambda} \approx 8.33 \cdot 10^{16} \, \mathrm{s}^{-1}$
