3. Different colors of light bend through different angles W.r.t the incident ray as they pass through the prism i.e., the angles of deviation are different for different colors. This results in dispersion of light.

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 […]

We do not see a dispersion of sunlight when it enters the air because the speed of various colors of light in the air is the same.

When white light passes through a prism, it splits up into its constituent colors. The phenomenon of splitting white light into its constituent colors is called dispersion of light. Here it is due to the refraction of white light by a prism.

5. When the spectrum of colors emerged from a prism is passed through another identical prism placed in an inverted position, a beam of white light emerges from it.

7. The water droplets refract and disperse the incident sunlight, then reflect it internally, and finally refract it again when it comes out of the raindrop, resulting in a spectrum of colors.

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 […]

White light is a mixture of all the colors (wavelengths) at equal intensities. It is nothing but colorless daylight. The sun and other stars produce white light. Artificially, white LEDs and fluorescent light bulbs produce and emit white light. The light given out by incandescent light bulbs is not white. If this white light is incident on a prism, a certain pattern of light is observed, about which we will be learning in this section.

When the spectrum of colors emerging from a prism is passed through another identical prism placed in an inverted position, a beam of white light emerges from it.

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 […]

4. Even if the wavelengths of different colored lights are different in the prism, their frequency is the same. The speed of red light is the highest and the speed of violet light is the lowest in the prism.

Dispersion of sunlight by the tiny water droplets present in the atmosphere forms the rainbow. Here, the water droplets act as small prisms and disperse light. They first refract and then disperse the incident sunlight, which is then reflected internally, and finally refracted again when it comes out of the raindrop.
