What is the frequency of a radiation with a wavelength of 3.0 × 10⁻⁵ m? (Speed of light = 3.0 × 10⁸ m/s) A) 1 × 10¹³ Hz B) 2 × 10¹³ Hz C) 1.1 × 10¹³ Hz D) 1.2 × 10¹³ Hz

Question

Quizplus · Accepted Answer

The frequency of a radiation is given by the speed of light divided by its wavelength. So, the frequency of a radiation with a wavelength of 3.0 × 10⁻⁵ m is:$$f = c/\lambda = (3.0 × 10^8 m/s)/(3.0 × 10^{−5} m) = 1 × 10^{13} Hz$$
