Question

The wavelength of green light from a traffic signal is centered at 5.20 x 10^-7 m. Calculate the frequency.

a) 1.52 x 10^14 Hz
b) 5.20 x 10^7 Hz
c) 3.00 x 10^8 Hz
d) 1.52 x 10^8 Hz

Answer 1

To calculate the frequency of green light, you can use the equation speed of light = wavelength x frequency. By rearranging the equation and substituting the values, we find that the frequency of green light is approximately 5.77 x 10^14 Hz.

Step-by-step explanation:

To calculate the frequency of green light, we need to use the equation:

speed of light = wavelength x frequency

Given that the wavelength of green light is 5.20 x 10^-7 m, we can rearrange the equation to solve for frequency:

frequency = speed of light / wavelength

Substituting the values, we get:

frequency = 3.00 x 10^8 m/s / 5.20 x 10^-7 m

Calculating this, we find that the frequency of green light is approximately 5.77 x 10^14 Hz.
