6. As the index of refraction of the surrounding is decreased by keeping it constant for the prism, it is observed that the angle of deviation decreases.

Prism

The light ray seems to bend towards the normal on entering the prism at the interface AB. The angle of incidence here is greater than the angle of refraction.

The angle between the incident ray produced and the emergent ray produced is called the angle of deviation (D). It is a measure of deviation of the incident ray from its actual path on emergence.

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: 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 […]

7. As the color of the incident light is changed from red to green and green to violet, it is observed that the angle of deviation increases on decreasing the wavelength of the incident light

1. A triangular glass prism has two triangular bases and three rectangular lateral surfaces. The angle between its two lateral surfaces is called the angle of the prism (A).

The light ray seems to bend away from the normal on emerging from the prism at the interface AC. The angle of incidence here is smaller than the angle of refraction (emergence, e).

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 […]

Which of the following would happen if the refractive index of the surrounding medium is equal to that of the material of the prism?

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 […]

2. The angle between the incident ray produced and the emergent ray produced is called the angle of deviation (D). It is a measure of deviation of the incident ray from its actual path on emergence.

A ray of light bends towards the normal when it gets into a denser medium and bends away from the normal on entering a rarer medium. This is true whenever light gets refracted at any interface separating any two mediums and it does not depend upon the shape of the surfaces or their inclination. This is true even when it gets refracted through a prism.

5. As the index of refraction of the material of the prism is decreased by keeping it constant for the surrounding, it is observed that the angle of deviation decreases.

Thus, it can be concluded that, refraction takes place at both the interfaces of a triangular prism, when light passes through it. However, the refraction of light through a triangular prism is somewhat different from that of the refraction through a glass slab.
