Quizplus · Accepted Answer

The frequency $ f $ can be calculated using the formula $ f = \frac{c}{\lambda} $, where $ c $ is the speed of light ($3 \times 10^8$ m/s) and $ \lambda $ is the wavelength (11.4 pm = 11.4 $\times$ 10^-12 m). This gives $ f = \frac{3 \times 10^8}{11.4 \times 10^{-12}} \approx 2.63 \times 10^{19} $ s^-1.
