Calculate the frequency of visible light having a wavelength of 686 nm. A)4.37 × 10¹⁴/s B)4.37 × 10⁵/s C)6.17 × 10¹⁴/s D)2.29 × 10^-15/s E)2.29 × 10^-6/s

Question

Quizplus · Accepted Answer

The frequency (f) of light is calculated using the formula f = c/λ, where c is the speed of light (approximately 3.00 × 10^8 m/s) and λ is the wavelength in meters. Converting 686 nm to meters gives 686 × 10^-9 m. Thus, f = (3.00 × 10^8 m/s) / (686 × 10^-9 m) = 4.37 × 10^14 /s.
