Using the equation frequency = wave speed/wavelength

use the wavelength is 656E-9 meters to calculate the frequency of this photon (remember the speed of light is 3E8 m/s)

A. 7.6E14 Hz

B. 6.0E14 Hz

C. 4.6E14 Hz

Expert Solution

Answer: C. 4.6E14 Hz

Step-by-step explanation

Frequency of photon is given by the relation:

f = c / L

where f = frequency of photon, L = wavelength of photon, c = speed of light.

put c = 3 x 10⁸ m/s and L = 656 x 10^-9 m in this equation and we get:

f = c / L = 3 x 10⁸ / (656 x 10^-9) = 4.573 x 10¹⁴ Hz

f = 4.6 x 10¹⁴ Hz

Therefore, C. 4.6E14 Hz is the correct answer.

Answer: C. 4.6E14 Hz
