explain luminious intensity and luminous flux give their units establish relation between them​

Answer 1

Answer:

hope it helps you

Explanation:

Luminous intensity should not be confused with another photometric unit, luminous flux, which is the total perceived power emitted in all directions. Luminous intensity is the perceived power per unit solid angle. ... The resulting beam is narrower and brighter, though its luminous flux remains unchanged.

Luminous flux, or luminous power, is the measure of the perceived power of light. ... The SI unit of luminous flux is the lumen (lm). One lumen is defined as the luminous flux of light produced by a light source that emits 1 cd of luminous intensity over a solid angle of 1 sr.
