OBJECTIVES To experimentally verify the malus’s law. PRINCIPLE Light, when modelled as a wave phenomenon, can be classified as a transverse electromagnetic wave consisting of oscillating electric and magnetic fields that are oriented perpendicular to each other. Depending on the orientation of the plane of polarization of the electric field with respect to the direction of propagation of the wave,…
Each Microslide title includes a slide featuring 8 related 35mm images photographed through a microscope called photomicrographs. Arrows and call outs help the student locate important features. Each Microslide is accompanied by a detailed lesson plan designed to stimulate, inform and question students about the topic under study. Each lesson plan has a pocket in which the Microslide is stored.

Objectives To study the photoconductivity of CdS Photoresistor, in the following conditions: Applied voltage vs photocurrent (IPH) at constant irradiance (Φ). Photocurrent (IPH) vs irradiance (Φ) at constant applied voltage (V). Principle The phenomenon of photoconductivity occurs when an incident light shown upon a semiconductor causes an increase in its electrical conductivity. This is because of excitation of electrons across…
Objectives: To determine the Planck’s constant using LED. Principle: Key Features: • Built-In Heater: The heating element is built in the system and is powered by 12V input. The efficient heating mechanism heats the system to required temperature in a few minutes with minimum power requirement of 40W. • Modular Design: The modular design of the setup allows testing of…
Students can quantitatively see how pressure on an object changes as it moves deeper under a fluid with this interactive density pressure manometer activity. A hollow drum covered with a rubber membrane is connected to an open-end manometer. When the drum is pushed under water the pressure on the rubber membrane increases the pressure inside the tubing, causing the manometer…
Objectives: To study the effect of wave plates on polarized light • Quarter wave plate • Half wave plate Principle: Waveplates are optical devices that resolves a light wave into two orthogonal linear polarization components by producing a phase shift between them. The transmitted light may have a different type of polarization than the incident beam due to the induced…
