Calculation of photons emitted by a 60-watt bulb in 10 hrs when light of wavelength 6000 Å is emitted by it
Step 1: Calculate the energy of a photon with wavelength 6000 Å
We know that energy of a photon is given by E=hc/λ, where h is Planck's constant, c is the speed of light, and λ is the wavelength of the light.
Plugging in the values, we get:
E= (6.626 x 10^-34 J s) x (3 x 10^8 m/s) / (6000 x 10^-10 m) = 3.31 x 10^-19 J
Step 2: Calculate the number of photons emitted in one second
Power is the rate at which energy is emitted or absorbed per unit time. The power of a 60-watt bulb is 60 J/s.
The number of photons emitted per second is given by the ratio of the power to the energy of one photon:
Number of photons per second = 60 J/s / 3.31 x 10^-19 J = 1.81 x 10^20 photons/s
Step 3: Calculate the number of photons emitted in 10 hours
Number of photons emitted in 1 hour = 1.81 x 10^20 photons/s x 3600 s/hour = 6.52 x 10^23 photons/hour
Number of photons emitted in 10 hours = 6.52 x 10^23 photons/hour x 10 hours = 6.52 x 10^24 photons
Therefore, the number of photons emitted by a 60-watt bulb in 10 hours when light of wavelength 6000 Å is emitted by it is 6.52 x 10^24 photons.
