How many photons per second are emitted by a 5.5-W LED light bulb, if the emission is at a wavelength of 550 nm?
~ 1.23E22 photons/s
~ 5.07E21 photons/s
~ 3.62E19 photons/s
~ 1.52E19 photons/s
~ 4.27E19 photons/s
energy of each photon
E = hc/L
now
Number of photons * energy in each / time = Power
N* E / t = P
(N/t) * hc/L = P
(N/t) * 6.626* 10^-34* 3* 10^8 / ( 550* 10^-9) = 5.5
N/t = 1.52* 10^19 photons /s

Comment before rate in case any doubt, will reply for sure.. goodluck
