Interference is possible in (a) light waves only (b) sound waves only (c) both light and sound waves (d) neither light nor sound waves

Answer: (c). Interference is superposition of two coherent waves, a property of all waves. Light (electromagnetic) and sound (mechanical) are both waves, so both show interference. So the answer is (c) both light and sound waves.
