Final answer:

To find the frequency of a photon, we can use the equation c = λ * ƒ, where c is the speed of light, λ is the wavelength, and ƒ is the frequency. By substituting the given values and solving the equation, we find that the frequency of the green light photon is approximately 5.99 × 10^14 Hz.

Step-by-step explanation:

To determine the frequency of a photon, we can use the equation:

c = λ * ƒ

Where c is the speed of light (approximately 3.00 × 10^8 m/s), λ is the wavelength of the light, and ƒ is the frequency.

Using the given wavelength of 501 nm (1 nm = 1 × 10^-9 m), we can convert it to meters: 501 nm = 501 × 10^-9 m. Plugging in these values into the equation, we can solve for the frequency:

3.00 × 10^8 m/s = (501 × 10^-9 m) * ƒ

Simplifying the equation, we find that:

ƒ = (3.00 × 10^8 m/s) / (501 × 10^-9 m) ≈ 5.99 × 10^14 Hz

Therefore, the frequency of the green light photon is approximately 5.99 × 10^14 Hz.
