Light Energy

Within this topic, we will focus on the light and its sources with the aid of multiple examples. Moreover, we will study their applications and significant role through visual content mentioned here.

This topic discusses the phenomenon of reflection, where a ray of light falls on a surface and gets reflected. According to its law, the incident ray, the reflected ray and the normal lie in the same plane and the angle of incidence is equal to the angle of reflection.

In this topic, the formation of a plane mirror is explained. It defines some terms related to surfaces, such as the silvered surface and the reflecting surface. It consists of an activity based on the reflection of light from a plane surface.

This topic defines a virtual image and a real image based on the property that whether or not they can be obtained on a screen. It also consists of a table that lists some differences between real and virtual images.

This topic explains the split of white light from the sun seen through a glass prism into a rainbow type pattern. It discusses the differences between the primary and secondary colours of light with the help of activities.

In this topic, we will learn about the shadows which are made by the objects when light falls on them. Besides, we will learn that shadows are formed only on a screen.

The topic describes the process of making a pinhole camera. We will also understand the mechanism behind the proper functioning of a pinhole camera.
