Question

The frequency of visible light having a wavelength of 568.8 nm.

a) 5.27 x 10¹4 Hz
b) 5.27 x 10¹3 Hz
c) 5.27 x 10¹5 Hz
d) 5.27 x 10¹6 Hz

Answer 1

The frequency of visible light with a wavelength of 568.8 nm is 5.27 x 10^14 Hz.

Step-by-step explanation:

The frequency of visible light with a wavelength of 568.8 nm can be calculated using the formula:

speed of light = frequency x wavelength

Given that the speed of light is approximately 3.0 x 10^8 m/s, we can convert the wavelength to meters:

568.8 nm = 568.8 x 10^-9 m

Using these values, we can rearrange the formula to solve for frequency:

frequency = speed of light / wavelength

Plugging in the values:

frequency = 3.0 x 10^8 m/s / 568.8 x 10^-9 m = 5.27 x 10^14 Hz
