1.	Calculate the number of photons emitted per second by a 10 W sodium vapour lamp. Assume that 50% of the consumed energy is converted into light. Wavelength of sodium light = 600 nm. Take h=6.6×10−34 Js and c=3×108ms−1
Answer» Calculate the number of photons emitted per second by a 10 W sodium vapour lamp. Assume that 50% of the consumed energy is converted into light. Wavelength of sodium light = 600 nm. Take $h = 6.6 \times 10^{- 34} J s a n d c = 3 \times 10^{8} m s^{- 1}$
