Calculate the number of photons emitted by a 60 W bulb per second, if 10% of the electrical energy supplied to an incandescent light bulb is radiated as visible light.

A light bulb is an incandescent source of light. A light bulb emits light

No .of photon emitted eery second from 60 W bulb will be ………

Calculate the number of photons emitted per second by a 10 W sodium vapour lamp. Assume that 60% of the consumed energy is converted into light. Wavelength of sodium light = 590 nm.

If 10% of the energy supplied to an incandescent light bulb is radiated as visible light, how many visible light photons are emitted by 200watt bulb? Assume wavelength of all visible photons to be 5000Å. Given h=6.6xx10^(-34)Js .

Only a fraction of the electrical energy supplied to a tungsten light bulb is converted into visible light. If a 100 W light bulb converts 20% of the electrical energy into visible light (lambda=662.6nm) , then the number of photons emitted by the bulb per second is
