Ray Optics and Optical Instruments

This topic covers concepts such as Optics, Geometrical Optics, Speed of Light, Ray of Light and Beam of Light.

This topic covers concepts such as Reflection of Light, Laws of Reflection of Light, First Law of Reflection, Second Law of Reflection, Reflection from a Plane Mirror, Spherical Mirror, Pole of Spherical Mirror, Center of Curvature in Mirrors, etc.

This topic covers concepts such as Refraction of Light, Absolute Refractive Index, Refracted Ray, Snell's Law, Relative Refractive Index, Refraction from Plane Surface, Refraction from Single Slab, Apparent Depth for One Liquid, etc.

This topic covers concepts such as Total Reflecting Prisms and Total Internal Reflection in Liquids.

This topic covers concepts such as Lens, Thin Lens, Lens Surface Nomenclature, Focal Length of Lens, Optical Centre, Principal Axis of Lens, Power of Lens, Thin Lenses in Contact, Convex Lens, Ray Diagrams in Convex Lens, etc.

This topic deals with the concept of refraction through a prism. It explains how to derive a formula to calculate the angle of deviation of light through a prism and plot a graph for the same. The concept is explained clearly in a step-by-step manner.

In this topic, we will learn about the deviation and dispersion of light by a prism. Different types of prisms to bend rays or to invert image without changing its size are also highlighted here.

This topic covers concepts such as Total Internal Reflection in Rainbow, Formation of Primary Rainbow and Formation of Secondary Rainbow.

In this topic, we will learn about scattering of light, a phenomenon of the radiation of light in all possible directions after being absorbed by a particle of diameter larger than the wavelength of light. The sun appears yellow due to this phenomenon.

This topic covers concepts such as Optical Instruments, Microscopes, Simple Microscope, Compound Microscope, Eyepiece of Microscope, Objective of Microscope, Ray Diagrams for Microscope, Magnifying Power of Microscope, Telescope, etc.
