Physics Question on Waves
Beats are the result of
A
diffraction
B
destructive interference
C
constructive bid destructive interference
D
superposition of two waves o f nearly equal frequencies
Answer
superposition of two waves o f nearly equal frequencies
Explanation
Solution
Beats is the superposition of two waves of nearly equal frequencies. When the two tones are close in pitch but not identical, the difference in frequency generates the beating. The volume varies like in a tremolo as the sounds alternately interfere constructively and destructively.
