प्रश्न
The phenomenon of beats can take place
विकल्प
for longitudinal waves only
transverse waves only
for both longitudinal and transverse waves
for sound waves only
उत्तर
for both longitudinal and transverse waves
When two or more waves of slightly different frequencies (v1 – v2 ≯ 10) travel with the same speed in the same direction, they superimpose to give beats. Thus, the waves may be longitudinal or transverse.
