Introduction: Visible Light: Visible light from the Sun comes to Earth as white light traveling through space in the form of waves. Visible light contains a mixture of wavelengths that the human eye can detect. Visible light has wavelengths between 0.7 and 0.4 millionths of a meter. The different colors you see are electromagnetic waves […]

Introduction: Nowadays magnets are widely used for many applications. In this session, we will discuss the basics of magnets and their properties, and the way they were and are used. Explanation: Magnets: Magnetic and Non-magnetic Materials: Poles of a Magnet: Fig No. 1.2: Poles of a magnet Compass: Interaction Between Magnets: The north pole of […]

Introduction: We can’t directly observe many waves like light waves and sound waves. The mechanical waves on a rope, waves on the surface of the water, and a slinky are visible to us. So, these mechanical waves can serve as a model to understand the wave phenomenon. Explanation: Types of Waves: Fig:1 Types of waves […]

Introduction: In a tug of war, the one applying more force wins the game. In this session, we will calculate this force that makes one team win and one team lose. We will learn about it in terms of balanced force and unbalanced force. Explanation: Force Force is an external effort that may move a […]

The two laws of reflection also hold for the reflection from spherical surfaces. In other words, the incident ray, the reflected ray and the normal at the point of incidence all lie on the same plane and also the angle of incidence and the angle of reflection are equal to each other for spherical mirrors as well.

An object reflects certain amount of light falling on it. When this reflected light enters our eyes, we are able to see it. A transparent glass object lets almost all the light falling on it to pass through. That’s why we are able to see through it. Opaque objects do not let light to pass through themselves. They absorb and reflect most light that falls on them. A mirror reflects most of the light that falls on its surface. That’s why it is able to produce an image of an object. Generally, highly polished surfaces reflect more amount of light falling on them. In this section we will be looking at the reflection of light from various surfaces.

If the inner concave surface is silvered, the outer convex surface is capable of reflecting light. This mirror in which the convex surface is the reflecting surface is called a convex mirror.

The inner surface of the piece is called the concave surface and the outer bulged out surface is called the convex surface.

An incident ray hitting the reflecting surface is said to be incident normally on the surface if it goes along the normal
