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

In one joule of energy, the number of photons with have number equal to x is

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

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

Two monochromatic beam A and B of equal intensity I, hit a screen. The number of photons hitting the screen by beam A is twice that by beam B. Then what inference can you make about their frequencies?

For a moving object the distance covered by it is always greater than or equal to the displacement of the object in a given time interval . Comment .

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?
