Question
In interference and diffraction, the light energy is redistributed. If it reduces in one region, producing a dark fringe, it increases in another region, producing a bright fringe.
A. As there is no gain or loss of energy, these phenomena are consistent with the principle of conservation of energy.
B. Diffraction and interference are characteristics exhibited only by light waves.
Choose the correct answer from the options given below:
Options
A.A is true and B is also true
B.A is false, but B is true
C.A is true, but B is false
D.Both A and B are false
Solution
Sol. [Key Concept: Interference/diffraction — energy is redistributed, conserved] In interference and diffraction there is no loss of energy, the energy gets redistributed.
Interference and diffraction both are exhibited in light as well as sound waves.
