A string of length l, fixed at both ends, vibrates in its fundamental mode. Transverse waves can travel along the string with a velocity V. Sound waves travel in air with a velocity v. The wavelength, in air, of the sound produced by the string is(a) 2lv/v(b) 2lV/v(c) lV/v(d) 2l |
|
Answer» Correct Answer is;(a) 2lv/v The frequency of sound emitted is n = V/2l. The wavelength of sound in air is v/n = 2lv/V. |
