Electromagnetic waves that have a wavelength of 300 m in free space have a frequency of A) 1 × 10^-³ Hz. B) 5 × 10⁵ Hz. C) 1 × 10⁶ Hz. D) 9 × 10⁶ Hz. E) 1 × 10¹¹ Hz.

Question

Quizplus · Accepted Answer

The speed of light in free space is approximately 3 × 10^8 m/s. The frequency of the electromagnetic waves is given by the equation f=c/λ, where c is the speed of light and λ is the wavelength. Plugging in the values, we get f=3 × 10^8/300 = 1 × 10^6 Hz = 1 × 10^16 Hz. Therefore, the answer is C.
