BEATS - SUPERPOSITION OF WAVES Now when the tension of the string is slightly increased the number of beats reduces to 2 2 per second. Assuming the velocity of sound in air to be 340 m/s, the frequency n n of the tuning fork (in Hz) is, Solution: The third harmonic in a pipe closed at one end occurs at a frequency, ν = 3v/(4L) = 3×340/(4×0.75) = 340 Hz. ν = 3 v / ( 4 L MULTIPLE IMAGES WITH PLANE MIRRORS Place a lighted candle in the space between the two mirrors. You will see single image of the candle in mirror. Reduce the angle between mirrors and observe multiple images of the candle which makes a beautiful scene. Now, measure the maximum angle between two mirrors when you get 1, 3, 5, 7, and 9 images. These angles are θ measured . WHY WATER RISE IN BURNING CANDLE EXPERIMENT The water rise in the burning candle experiment needs a proper explanation. The height of water rise depends on the candle size as well as for how long the candle is burned before putting the glass over it. The explanation is based on the thermal contraction of air inthe glass.
A SMALL MASS M IS ATTACHED TO A MASSLESS STRING WHOSE Problem: A small mass m is attached to a massless string whose other end is fixed at P as shown in the figure. The mass is undergoing circular motion in the x-y plane with centre at O and constant angular speed $\omega$. If the angular momentum of the system, calculated about O and P are denoted by $\vec{L}_{O}$ and $\vec{L}_{P}$, respectively, then (IIT JEE 2012) THE TORQUE Τ ON A BODY ABOUT A GIVEN POINT The Torque τ on a Body about a Given Point is : Important Problem.

Problem: The torque →τ τ → on a body about a given point is found to be equal to →A × →L A → × L →, where →A A → is a constant vector and →L L → is the angular momentum of the body about that point. From this its PHYSICS FORMULAS FOR CLASS 11 AND 12 Physics formulas from Mechanics, Waves and Oscillations, Optics, Heat and Thermodynamics, Electricity and Magnetism and Modern Physics.

The object distance u u, image distance v v and focal length f f are related by the mirror formula: 1 v + 1 u = 1 f 1 v + 1 u = 1 f. The magnification is the ratio of image height to the object height and it is given by m = − v u m = − v u.
