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
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
