The Doppler Effect is widely used in weather forecasting, medical imaging, radar, and astronomy. This kit makes it possible to create a Doppler Effect in an easy way, promoting the study of the frequency change due to movement changes. Requires a AA battery. Activity guide included. Ages 7+.
Objectives: To find the energy band gaps for different semiconductor diodes and LEDs Principle: At absolute zero-degree temperature, semiconductors are pure insulators. As the temperature is increased thermal energy create vibrations in crystal lattice and few electrons, which acquire sufficient vibrational energy break their covalent bond, become free, and move to the conduction band. The energy required to rapture the…
OBJECTIVES: Observe the effect of a magnetic field on plane of polarization of polarized light as it passes through a dispersive medium. Measure the Verdet’s constant of a given dispersive material. PRINCIPLE When a linearly polarized light passes through an optical medium in a region of strong magnetic field, the plane of polarization of linearly polarized light rotates by an…
Just Tubes is an assortment of 3 different types of test tubes: glass, plastic, and safety. Test tubes are one of the most widely used tools for performing science experiments. In chemistry, the test tube is used to hold, mix, or heat small quantities of chemicals while performing experiments. For biology, the test tube is used to handle and cultivate…

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…
