To determine the value of (the ratio of two specific heats of gas) for air by Clement and Desorme’s method

Apparatus Required:Large flask of capacity, 5 liters,liquid manometer, and a compression pump

A light-emitting diode (LED) is a semiconductor light source. Like a normal diode, the LED consists of a chip of semiconducting material doped with impurities to create a pn junction. As in other diodes, current flows easily from the p-side, or anode, to the n-side, or cathode, but not in the reverse direction. Charge-carriers—electrons and holes—flow into the junction from electrodes with different voltages. When an electron meets a hole, it falls into a lower energy level, and releases energy in the form of a photon. The wavelength of the light emitted, and therefore its color, depends on the band gap energy of the materials forming the p-n junction. Typical I-V Characteristics of LED in forward bias are shown in the fig. A laser diode is a laser where the active medium is a semiconductor similar to that found in a light-emitting diode. A laser diode, like many other semiconductor devices, is formed by doping a very thin layer on the surface of a crystal wafer. The crystal is doped to produce an n-type region and a p-type region, one above the other, resulting in a p-n junction, or diode. PROCEDURE: LEDs are connected in forward bias arrangement and applied voltage across LED is varied & corresponding current is measured. Result is tabulated and plotted on the graph. In second part voltage applied across Laser diode is varied and it’s corresponding output is measured & plotted.

To determine the frequency of an electrically maintained tuning fork by,

1. Transverse mode of vibration

2. Longitudinal mode of vibration

Electrically maintained tuning fork, fine thread, scale pan, weights and metre scale.

Speed of waves in a stretched string: A string means a wire or a fiber which has a uniform diameter and is perfectly flexible. The speed of a wave in a flexible stretched string depends upon the tension in the string and mass per unit length of the string.

Longitudinal mode- In this arrangement the tuning fork is set in such a manner that the vibrations of the prongs are parallel to the length of the string.
