A 1 cm long string vibrates with fundamental frequency of 256 Hz . If the length is reduced to 1/4 cm keeping the tension unaltered, the new fundamental frequency will be (in Hz) A 1 cm long string vibrates with fundamental frequency of 256 Hz . If the length is reduced to 1/4 cm keeping [...]

Consider the three waves z1 z2 and z3 as z1 = A sin (kx – ωt) z2 = A sin (kx + ωt) z3 = A sin (ky – ωt) Which of the following represents a standing wave? Consider the three waves z1 z2 and z3 as z1 = A sin (kx – ωt) z2 [...]

Stationary waves of frequency 300Hz are formed in a medium in which the velocity of sound is 1200 metre/sec. The distance between a node and the neighbouring antinode is Stationary waves of frequency 300Hz are formed in a medium in which the velocity of sound is 1200 metre/sec. The distance between a node and the [...]

First overtone frequency of a closed organ pipe is equal to the first overtone frequency of an open organ pipe. Further nth harmonic of closed organ pipe is also equal to the nth harmonic of open pipe, where n and m are First overtone frequency of a closed organ pipe is equal to the first [...]

Two identical strings are stretched at tensions TA and TB. A tuning fork is used to set them in vibration. A vibrates in its fundamental mode and B in its second harmonic mode then Two identical strings are stretched at tensions TA and TB. A tuning fork is used to set them in vibration. A [...]

A tuning fork of frequency 340 Hz is sounded above a cylindrical tube 1m long. water is slowly poured into the tube. If the speed of sound is 340m/s at what levels of water in the tube will the sound of the tuning fork be appreciably intensified ? how many nodes and antinodes are set [...]

If you set up the seventh harmonic on a string fixed at both ends, how many nodes and antinodes are set up in it ? how many nodes and antinodes are set up in it ? If you set up the seventh harmonic on a string fixed at both ends November 1, 2020 Category: Arihant [...]

The vibrations of a string of length 60 cm fixed at both ends are represented by the equation y=4sin( 15/πx ) cos (96πt) where x and y are in cm and ‘t’ in seconds. the maximum displacement at x = 5 cm is the air column in the pipe can resonate for sound of frequency [...]

Velocity of sound in air is 320m/s. A pipe closed at one end has a length of 1 m. Neglecting the end corrections, the air column in the pipe can resonate for sound of frequency. the air column in the pipe can resonate for sound of frequency : Velocity of sound in air is 320m/s. [...]

A tube closed at one end and containing air produces, when excited the fundamental note of frequency 512 Hz. If the tube is open at both ends, the fundamental frequency that can be excited is (in Hz) A tube closed at one end and containing air produces the fundamental frequency that can be excited is [...]
