A beam of light from a laser has a wavelength of 600 nm.What is the frequency of this light? A) 5*10¹⁴ Hz B) 6000 Hz C) 3*10⁸ m/s D) 2* ^- ¹⁵ Hz E) 1.8*0¹² Hz

Question

Quizplus · Accepted Answer

The frequency of light is given by the equation f = c/λ, where c is the speed of light and λ is the wavelength. In this case, the wavelength is 600 nm, which is equal to 600 x 10^-9 meters. The speed of light is 3 x 10^8 meters per second. Plugging these values into the equation, we get f = (3 x 10^8 m/s) / (600 x 10^-9 m) = 5 x 10^14 Hz.
