Class 12 Physics (India): How telescopes work

Let's explore how telescopes work intuitively using a demo. Then we will talk about some nuances involved in drawing ray diagrams and derive an expression for magnifying power. 

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.

Optic instruments: telescopes and microscopes

Microscopes and telescopes seem to work like magic. But it isn't magic, it's just that they use the properties of light. In this section, we will build telescopes and compound microscopes intuitively. We will also explore how an everyday magnifying glass really works.
