Light that has a wavelength of 600 nm has a frequency of A)5.0 $\times$ 10¹⁵ Hz B)5.0 $\times$ 10¹⁴ Hz C)5.0 $\times$ 10⁶ Hz D)1.2 $\times$ 10⁵ Hz E)1.2 $\times$ 10¹⁴ Hz

Question

Quizplus · Accepted Answer

The frequency of light is related to its wavelength by the equation f=c/λ, where c is the speed of light. Plugging in the given values yields: f = (3.00 x 10^8 m/s)/(600 nm x 10^-9 m/nm) = 5.0 x 10^14 Hz. Converting from scientific notation to regular notation, the frequency is 500,000,000,000,000 Hz, which can be written as 5.0 x 10^14 Hz or 5.0 x 10^10 MHz. The only choice that matches this frequency is B.
