Final answer:

The frequency of the light emitted by the green laser pointer is approximately 5.57 x 10^14 Hz.

Step-by-step explanation:

Frequency and wavelength are related through the equation:

c = λν

Where c is the speed of light, λ is the wavelength, and ν is the frequency.

To find the frequency of the light emitted by the green laser pointer, we can rearrange the equation as:

ν = c / λ

Given that the wavelength is 538 nm and the speed of light is approximately 3.00 x 10^8 m/s, we can substitute the values into the equation:

ν = (3.00 x 10^8 m/s) / (538 x 10^-9 m)

Simplifying:

ν ≈ 5.57 x 10^14 Hz

Therefore, the frequency of the light emitted by the green laser pointer is approximately 5.57 x 10^14 Hz.
