The wavelength of light visible to the human eye is on the order of 5 × 10⁻⁷ m. If the speed of light in air is 3 × 10⁸ m/s, find the frequency of the lightwave. A)3 × 10⁷ Hz B)4 × 10⁹ Hz C)5 × 10¹¹Hz D)6 × 10¹⁴ Hz E)4 × 10¹⁵ Hz

Question

Quizplus · Accepted Answer

We can use the formula:

speed of light = wavelength x frequency

Rearranging this formula, we get:

frequency = speed of light / wavelength

Substituting the given values, we get:

frequency = (3 × 10^8 m/s) / (5 × 10^-7 m)

frequency = 6 × 10^14 Hz

Therefore, the frequency of the lightwave is 6 × 10^14 Hz, which is closest to option D (6 × 10^14 Hz).
