If the tension and diameter of a sonometre wire of fundamental frequency ‘f’ are doubled and density is halved then its fundamental frequency will become: If the tension and diameter of a sonometre wire of fundamental frequency 'f' are doubled and density is halved then its fundamental frequency will become: September 17, 2020 Category: Cengage [...]

A sonometre wire vibrates with frequency n. It is replaced by another wire of three times the diameter, if tension and other parameters remain the same, the frequency of vibration of the wire will be A sonometre wire vibrates with frequency n. It is replaced by another wire of three times the diameter if tension [...]

Two travelling waves y1 = A sin [k (x – ct) ] and y2 = A sin [k( x + ct) ] are superimposed on string. The distance between adjacent nodes is Two travelling waves y1 = A sin [k (x – ct) ] and y2 = A sin [k( x + ct) ] are [...]

A wave disturbance in a medium is described by y (x,t) = 0.02 cos (50πt+π/2) cos (10 πx) where x and y are in meter and t is in second` A wave disturbance in a medium is described by y (x t) = 0.02 cos (50πt+π/2) cos (10 πx) where x and y are in [...]

A wave represented by the equation y=a cos(kx−ωt) is superposed with another wave to form stationary wave such that the point x=0 is a node. The equation for the other wave is A wave represented by the equation y=a cos(kx−ωt) is superposed with another wave to form stationary wave such that the point x=0 is [...]

Two pulses in a stretched string whose centers are initially 8 cm apart are moving towards each other as shown in the figure. The speed of each pulse is 2 cm/s. After 2 seconds, the total energy of the pulses will be the total energy of the pulses will be Two pulses in a stretched [...]

A wave pulse traveling on a two piece string, gets partially reflected and partially transmitted at the junction. The reflected wave is inverted in shape as compared to incident one. If the incident wave has wavelength λ and transmitted wave has λ′, 4mm and 7mm arrive at a given point with successive phase difference is [...]

A wave pulse is travelling along a taut string fixed to a heavy wall. After reflection from the wall the string might shown the wave pulse as A wave pulse is travelling along a taut string fixed to a heavy wall. After reflection from the wall the string might shown the wave pulse as September [...]

Consider ten identical sources of sound all giving the same frequency but having phase angles which are random. If the average intensity of each source is I0​ the average of resultant intensity due to all these ten sources will be 4mm and 7mm arrive at a given point with successive phase difference is pie/2.The amplitude [...]
