A wire is stretched between two bridges ...

A wire is stretched between two bridges A and B. A small piece of paper of shape A (called rider) is placed at the middle of the wire. When the stem of a tuning fork P is placed at the bridge A the rider only vibrates, but it flies away when another tuning fork Q is placed. Explain the difference.

The diagram above shows a wire stretched over a sonometer. Stems of two vibrating tuning forks A and B are touched to the wooden box of the sonometer. It is observed that the paper rider (a small piece of paper folded at the centre) present on the wire flies off when the stem of vibrating tuning fork B is touched to the wooden box but the paper just vibrates when the stem of vibrating tuning fork A is touched to the wooden box. Why does the paper rider fly off when the stem of tuning fork B is touched to the box ?

The diagram below shows a wire stretched over a sonometer. Stems of two vibrating tuning forks A and B are touched in turn to the wooden box of the sonometer. It is observed that the paper rider (a small piece of paper folded at the centre) present on the wire flies off when the stem of vibrating tuning fork B is touched to the wooden box but the paper just vibrates when the stem of vibrating tuning fork A is touched to the wooden box. Name the phenomenon when the paper rider just vibrates.

(a). Find the magnetic field B at point O (centre) of (i). ABCD, which is a square of side l. (ii). ABC, which is an equilateral triangle of side l. (b) Twelve uniform wires of equal length l and each of resistance r are connected to form a skelton cube. A battary of emf E is connected between two diagonally opposite corners of the cube. The magnetic induction at the centreof the cube is ......... (c) An infinately long straight wire is placed at the origin along the z-axis. The current I flows along the positive z-axis. Find the unit vecotrs showing the direction of magnetic field at the four points: P(a,0), Q(0,b), R(a,0) and S(0,-b)

A sonometer wire resonates with a given tuning fork forming standing waves with three antinodes between the two bridges when a mass of 16 Kg is suspended from the wire. When this mass is replaced by a mass .9 kg. the wire resonates with the same tuning fork for .p. antinodes for the same positions of the bridges. Then .p. is

Figure shown a clamped metal string of length 30 cm and linear mass density 0.1 kg //m . Which is taut at a tension of 40N . A small rider ( piece of paper ) is placed on string at point P as shown. An external vibrating tuning fork is brought near this string and oscillations of rider are carefully observed. Now if the tension in the string is made 160N , at which of the following frequencies of turning fork , rider will not vibrate at all

In Fig. , A, B, C and D represent the test tubes each of height 20 cm which are filled with water up to heights of 12 cm, 14 cm, 16 cm and 18 cm respectively. If a vibrating tuning fork is placed over the mouth of test tube D, a loud sound is heard. Describe the observations with the tubes A, B and C when the vibrating tuning fork is placed over the mouth of these tubes.

The total length of a sonometer wire fixed between two bridges is 110 cm. Now, two more bridges are placed to divide the length of the wire in the ratio 6:3:2 . If the tension in the wire is 400 N and the mass per unit length of the wire is "0.01 kg m"^(-1) , then the minimum common frequency with which all the three parts can vibrate, is

Young's double-slit experiment setup with ligth of wavelength lambda = 6000 Å , distance between two slit in 2 mm and distance between the plane of slits and the screen. Is 2 m. The slits are of equal intensity. When a sheet of glass of refractive index 1.5 (which permtis only a fraction eta of the incident light to pass through) and thickness 8000 Å is placed in front of the lower slit, it is observed that the intensity at a point P, 0.15 mm above the central maxima, does not change. The phase difference at point P without inserting the slab is
