Is it always true that for two sources of equal intensity, the number of photons emitted in a given time are equal?

A red bulb and violet bulb of equal power emits n_(R ) and n_(v) number of photons in a given time, then

A red bulb and violet bulb of equal power emits n_(R ) and n_(v) number of photons in a given time, then

When the intensity of a light source is increased (a) the number of photons emitted by the source in unit time increases (b) the total energy of the photons emitted per unit time increases (c) more energetic photons are emitted (d) faster photons are emitted

In Young s double slit experiment, the phase different between two coherent sources of equal intensity is π/3.The intensity at a point which is at equal distance from the two slits is (l0 is maximum intensity)

A radio transmitter operates at a frequency of 300 KHz and a power of 10 KW. The number of photons emitted per second is approximately equal to

A monochromatic source emits light of wavelength 550 nm is emitted by a source . Find the number of photons emitted by the source in 90 seconds if power of source is 60 W.

Atomic number is always equal to the number of electrons present in an atom. True/False explain.

Why two light sources must be of equal intensity to obtain a well-defined interference pattern?
