Types of radioisotopes and their examples
Radioisotopes are formed by Isotopes, which are atoms with the same atomic number and different mass numbers. Some Types of radioisotopes are Radioactive sodium carbon, phosphorous, Iodine, Gold. Radioisotopes examples Examples of natural radioisotopes are 238 U (uranium), 40 K (potassium), 232 Th (thorium) and their child nuclei (obtained by…

Image formation by convex and concave lens ray diagrams
How convex and concave lens work? In mirrors, images are formed through reflection but lenses form images through refraction. This is explained with the help of ray diagrams as follows: Image formation by convex lens ray diagrams Image formation in…

What is Radioactive Decay?
Nuclei are made up of protons and neutrons, which are held together by the so-called strong force. Some nuclei have a combination of protons and neutrons that do not lead to a stable configuration. These nuclei are unstable or radioactive. Unstable nuclei tend…

Polarization of light types and examples
What is polarization of light? Separation of light waves with electric field vector oriented only in a single direction is called polarization of light or this is a process in which light and other radiations are restricted to vibrate in…

What are Different types of Diode?
A diode is a two-terminal device formed by two doped regions of silicon separated by a PN junction. The most common category of the diode, known as the general-purpose diode, is covered. Zener diode, PN junction diode, Tunnel diode, Varactor diode, Schottky diode,…

5 band resistor colour code
Carbon resistors are most common in electronic equipment. They consist of a high-grade ceramic rod or cone ( called the substrate on which is deposited a thin resistive film of carbon. The numerical value of their resistance is indicated by…

Structure of atom for class 9 and 11
what is Atom? “Atom is the smallest particle of an element that possesses the unique characteristics of that element.” All matter is composed of atoms; all atoms consist of electrons, protons, and neutrons except normal hydrogen, which does not have…

Reflection of Light Examples in daily life
What is reflection of light? When light from one medium falls on the surface of another medium, it bounces back in the same medium such that the angle of incidence is equal to the angle of reflection. There are two…
