Question

What is the frequency of green light with a wavelength of 520 nm?

a) 5.77 × 10¹⁴ Hz
b) 5.77 × 10¹² Hz
c) 5.77 × 10¹⁶ Hz
d) 5.77 × 10¹⁵ Hz

Answer 1

The frequency of green light with a wavelength of 520 nm is approximately 5.77 × 10^14 Hz.

Step-by-step explanation:

The frequency of green light with a wavelength of 520 nm can be found using the equation: frequency = speed of light / wavelength. The speed of light, c, is approximately 3.0 × 10^8 m/s. Converting the wavelength to meters, we have 520 nm = 520 × 10^(-9) m. Substituting the values into the equation, we get:

frequency = (3.0 × 10^8 m/s) / (520 × 10^(-9) m)

Calculating this gives us a frequency of approximately 5.77 × 10^14 Hz. Therefore, the correct answer is option a) 5.77 × 10^14 Hz.
