Worried about the mid-term exams? Want help revising your Physics concepts? Join this online class now! In this session, your favourite BYJU’S educator, Saurabh Sir, revises all the important concepts about the human eye. This is an important topic in your class 10 Chapter 11, The Human Eye and the Colourful World.

The human eye is one of the most valuable and sensitive sense organs. It helps you to see all the beautiful things including colours and shapes around you. The human eye works just like a camera. Its lens system forms an image on a light-sensitive screen called the retina.

Some of the topics discussed in this class are as follows:
1. Dispersion by a prism
2. Rainbow Formation
3. Atmospheric refraction
4. Twinkling of stars
5. Advanced sunrise and delayed sunset
6. Tyndall effect
7. Scattering of light

The phenomenon of scattering of light by the colloidal particles gives rise to the Tyndall effect. This phenomenon is seen when a fine beam of sunlight enters a smoke-filled room through a small hole. Thus, the scattering of light makes the particles visible. Tyndall effect can also be observed when sunlight passes through a canopy of a dense forest. Join this class to learn more about the structure of the human eye.
