When a string fixed at its both ends vibrates in 1 loop, 2 loops, 3 loops and 4 loops, the frequencies are in the ratioA. 1 : 1 : 1 : 1B. 1 : 2 : 3 : 4C. 4 : 3 : 2 : 1D. 1 : 4 : 9 : 16 |

Answer» Correct Answer - B When the string vibrates in loops n, its frequency is, `upsilon_(n)=(nv)/(2L)` where L is the length of the string and v is the velocity of the wave `therefore` When the string fixed at its both ends vibrates in 1 loop. 2 loops, 3 loops and 4 loops, the frequencies are in the ratio 1:2:3:4. |
