A wave of frequency 100 Hz is sent along a string towards a fixed end. When this wave travels back after reflection, a node is formed at a distance of 10 cm from the fixed end of the string. The speed of the incident (or reflected) wave is


Correct option is

20 ms–1


The fixed end is a mode. So the distance between two consecutive nodes  . The speed of the waves is




The intensity of a sound wave falls by 10% in travelling a distance of 1 metre in a medium. If the initial intensity of the sound wave was 100 decibels, its value after it passes through 3 metres thickness of the medium will be


A tube closed at one end 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 in (in Hz)


Two second waves of equal intensity I produce beats. The maximum intensity of sound produced in beats will be


Two waves of wavelength 2 m and 2.02 m moving with the same speed superpose to produce 2 beats per second. The speed of each wave is


The potential energy of a particle executing simple harmonic motion at a distance x from the equilibrium position is proportional to



Two travelling waves



are superposed on a string. The distance between adjacent nodes is


If the amplitude of a sound wave is doubled and its frequency reduced to one-fourth, the intensity of sound at the same point will


At a certain instant a stationary transverse wave is found to have maximum kinetic energy. The appearance of the string at that instant is a



The displacement y of a particle executing simple harmonic motion is given by 


The expression may be considered to be a result of the superposition of how many simple harmonic motions?


A particle starts simple harmonic motion from the mean position O as shown in the figure. Its amplitude is A and its time period is T. At a certain instant, its speed is half its maximum speed. At this instant, the displacement x is
