Light is an electromagnetic wave and travels at a speed of 3.00 108 m/s. The human eye is most sensitive to yellow-green light, which has a wavelength of 5.58 10-7 m. What is the frequency of this light?

Ever heard of the equation
(wavelength) x (frequency) = wave speed?

Use it to get the answer.

1 answer

Yes, we can use the equation:

(wavelength) x (frequency) = wave speed

We are given the wavelength (5.58 x 10^-7 m) and the wave speed (3.00 x 10^8 m/s), and we need to find the frequency. We can rearrange the equation to solve for frequency:

frequency = wave speed / wavelength

frequency = (3.00 x 10^8 m/s) / (5.58 x 10^-7 m)

frequency = 5.38 x 10^14 Hz

So the frequency of yellow-green light is approximately 5.38 x 10^14 Hz.
