Use of multimeter Aim Use of multimeter to see the unidirectional flow of current in case of a diode and an LED and check whether a given electronic component (e.g., diode) is in working order. Apparatus and Material Required Principle Diode: A diode is a two-terminal semiconductor device that allows current to flow in only one…

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…
