A given sitar string is observed to produce beats when sounded with a given standard source of frequency 'N'. It is given that 'N' is greater than the frequency of the note being produced by the sitar string. The tension of this sitar string is slightly increased. Will the beat frequency increase or decrease? Justify your answer.

answer : the beat frequency increases
explanation : A given sitar string is observed to produce beats when sounded with a given standard source of frequency 'N'. It is given that 'N' is greater than the frequency of the note being produced by the sitar string. The tension of this sitar string is slightly increased.
we know, Frequency increases with a increase in the tension in a string. This is because frequency is directly proportional to the square root of tension. It is given as: f ∝ √T
so, beat frequency will increase.
