Before playing the orchestra in a musical concert, a sitarist tries to adjust the tension and pluck the string suitably. By doing so, he is adjusting:

(a) intensity of sound only

(b) amplitude of sound only

(c) frequency of the sitar string with the frequency of other musical instruments

(d) loudness of sound

Answers (1)

Answer: C

Solution:

The frequency of sound generated from the string, depends on the length of the string, the tension in the string as well as thickness of the string.

Hence, by adjusting the strings of sitar, the Sitarist adjusts frequency with other musical instruments.

Loudness, intensity or amplitude all represent the same physical phenomenon and it depends on how hard you strike the string.

Hence the correct option is option C
