Let `(n_r) and (n_b) be respectively the number of photons emitted by a red bulb and a blue blub of equal power in a given time.

If N_(red) and N_(Blue) are the numbers of photons emitted by respective sources of equal power and equal dimensions in unit time, then

Two bulbs 'A' and 'B' emit red light and yellow light at 8000 "Å" and 4000 "Å" respectively. The number of photons emitted by both the bulbs per second is the same. If the red bulb is labelled as 100 watts, find the wattage of the yellow bulb.

If n_(r ) and n_(b) are the number of photons of red and blue light respectively with same energy, then

Two bulbs A and B are emitting monochromatic light of wavelength such that A can just ionise H atom and B can just ionise He^(+) ions. If the power of A and B are 30 W and 40 W respectively , the ratio of number of photons emitted per second by bulb A to bulb B is :

n_(R) and n_(g) give the number of photons in red and green beams of light. If the two beams have the same energy, then

The maximum number of photons emitted when an electron jumps from an energy level n=5 to n=1 is s

The maximum number of photons emitted when an electron jumps from an energy level n=4 to n=1 is
