The phenomenon of interference is based on (a) conservation of momentum (b) quantum nature of light (c) conservation of energy (d) conservation of charge

Answer: (c). In interference energy is only redistributed: less at dark fringes, more at bright fringes. The average intensity stays I₁ + I₂, so total energy is conserved. So the answer is (c) conservation of energy.

The phenomenon of interference is based on

Show answer and solution

Answer: (c)

In interference energy is only redistributed: less at dark fringes, more at bright fringes.
The average intensity stays $I_1 + I_2$ , so total energy is conserved.
So the answer is (c) conservation of energy.
