Final answer:
The frequency of light with a wavelength of 625 nm is 4.8 × 10^14 Hz.
Step-by-step explanation:
The frequency of light can be calculated using the formula: frequency = speed of light / wavelength. The speed of light is a constant value of approximately 3 × 10^8 meters per second. To find the frequency of light with a wavelength of 625 nm, we need to convert the wavelength to meters by dividing it by 1 × 10^-9. The formula becomes:
frequency = (3 × 10^8 m/s) / (625 × 10^-9 m) = 4.8 × 10^14 Hz
