Class 12 Physics (India): Bohr model energy levels

Calculating electron energy for levels n=1 to 3. Drawing a shell model diagram and an energy diagram for hydrogen, and then using the diagrams to calculate the energy required to excite an electron between different energy levels. 

Class 12 Physics (India)

It is now time to dive deeper into the world of physics with topics from class 12 (NCERT) such as electrostatics, electricity, magnetism, electromagnetic induction, and electromagnetic waves. Let's also learn more about light with ray optics and wave optics. Finally, let's look at what happened in the last hundred years of physics by getting introduced to quantum mechanics with dual nature of radiation and matter, atoms, nuclei, and semiconductors.

Atoms and electrons

Sometimes people draw atoms like little solar systems, but they're way stranger than that. In this section you'll learn how electrons can have wavelengths, jump orbitals, and emit photons while in an atom.
