Question

Describe a simple experiment in which you can demonstrate beats (due to superimposition of sound waves).

• Try to keep the experiment simple and precise.

• You are allowed to use electronic devices during the experiment.

• Please show mathematical derivations of how beats are getting generated.

#Revision Q16​

Answer 1

Answer:

Beats are produced by the superposition of two waves of slightly different frequencies but identical amplitudes. ... This wave fluctuates in amplitude, or beats, with a frequency called the beat frequency. We can determine the beat frequency by adding two waves together mathematically.

Answer 2

The process by which green plants make their own food with the help of sunlight is called photosynthesis.

Hope it helps :)
