Answer:

The wavelength λ is the distance between successive peaks in a wave. The frequency f of a wave is the number of complete waves that pass a point in a given time. where c is the speed of light. In your case, λ = 522 nm = 522 × 10⁻⁹ m and c = 2.998 × 10⁸ m·s⁻¹

Answer: 5.747 * 10^14 Hz

Explanation:

Convert 522nm to m = 522 * 10^-9 m (since 1nm=10^-9m)

If c = wavelength * frequency, where c is the speed of light (3.0 * 10^8 m/s), then you can manipulate the equation to solve for frequency (f).

f = c / wavelength

Plug in the given numbers:

f = (3.0 * 10^8) / (10^-9)

f = 5.747 * 10^14 Hz
