C) 1,3,2....................
Answer:
red laser emits 1.42 times the number of photons of the blue laser, per unit of time
Explanation:
In order to calculate the rates of photon emission for both wavelengths, you take into account that the power of the light is given by the following formula:
(1)
That is, the power is the energy per time.
h: Planck's constant
c: speed of light
λ: wavelength of the light
The number of photons emitted per unit of time is given by:
P: power of the light
E: energy of the light
For the two wavelengths you have
(2)
Where you have use that P1=P2
Finally, you replace the values of the wavelengths in the equation (2):
Then, the red laser emits 1.42 times the number of photons emited by the blue laser
