Lateral Deviation of a Light Beam Aim To observe refraction and lateral deviation of a beam of light incident obliquely on a glass slab. Apparatus and Material Required Principle A ray of light incident on a rectangular glass slab bends at the interface of two optical media, here, air and the glass. The emerging ray out…
Aim To verify the laws of combination of resistances (series and parallel) using a metre bridge. Apparatus and Material Required Principle When two resistances \(R_1\) and \(R_2\) are connected in series, the resistance of the combination \(R_S\) is given by \[R_S = R_1 + R_2\] When these two resistances are connected in parallel, the resistance of…
To find the focal length of a Concave Mirror – Experiment. Aim To find the value of v for different values of u in case of a concave mirror and to find the focal length. Apparatus and Material Required Terms and Definitions Cartesian Sign Convention Principle If an object is at a distance \(u\) from the…
To determine the internal resistance of a given primary cell using potentiometer.
Aim To find resistance of a given standard resistor using metre bridge. Apparatus and Material Required Description of the Apparatus Meter BridgeMeter bridge consists of one-meter-long constantan wire with uniform cross-sectional area and three thick metal strips, two bent at ninety-degree angles. Mounted on a wooden board marked with a scale, these components create a setup…
