Question

a string vibrates in one loop its frequency is 25HZ if it moves in 2 loops then frequency is​

Answer 1

Answer:

When the string vibrates in loops n, its frequency is, υ

n = 2Lnν

where L is the length of the string and ν is the velocity of the wave.

∴ When the string fixed at its both ends vibrates in 1 loops, 2 loops 3 loops and 4 loops, the frequencies are in the ratio 1:2:3:4.
