5.08 * 10^[14] s^-1

Explanation:

Speed of light is equal to the product of wavelength and frequency. See photo attached.

By rearranging this, we can solve for the frequency of yellow lamp at 590 nm.

c = 3 *10^8 m/s
590 nm = 5.9*10^-7 m

v = c/ lambda
v = [3 *10^8 m/s]/[5.9*10^-7 m]

v = 5.08 * 10^[14] s^-1
