MCQs on Interference

MCQ. For destructive interference, path difference is

odd number of half wavelengths
even number of half wavelengths
whole number of wavelengths
even whole number of wavelengths
Answer A

MCQ. Constructive interference happens when two waves are

out of phase
zero amplitude
in phase
in front
Answer C

MCQ. Two waves with phase difference 180° have resultant of amplitude

one
zero
same as single wave
doubles single wave
Answer B

MCQ. If two waves are in phase and have same amplitude then resultant wave has

half of amplitude of single wave
same amplitude as single wave
twice of amplitude of single wave
thrice of amplitude of single wave
Answer C

MCQ. Extra distance travelled by one of waves compared with other is called

path
displacement
phase difference
path difference
Answer D
