Dispersion of Light

Q1: What is Dispersion of Light?

Answer:

When white light passes through a glass prism, it separates into its spectrum of colours (in order violet, indigo, blue, green, yellow, orange, and red), this process is known as Dispersion.

Q2: What is Prism?

Answer:

A prism is glass apparatus made of transparent glass. It has three rectangular lateral surfaces and two triangular faces that are inclined at an angle. It dispersed the white light passing through it.

Q3:What is Refraction of Light?

Answer:

When the light ray changes its medium of propagation its deviates from its path this phenomenon is called the refraction of the light.

Q4: What is the Difference between Reflection and Refraction of Light?

Answer:

Refraction of light is the change in the direction of light when it changes its propagation of the medium whereas reflection is the change in direction of the light after striking through a solid surface.

Q5: What are Examples of Refraction of Light?

Answer:

Various examples of the refraction of light are,

• Twinkling of Stars
• Formation of Rainbow
• Red light of the sky during sunrise and sunset

Q6: What is VIBGYOR Full Form?

Answer:

When the light ray is passed through the glass prism it gets deviated into the spectrum of the light in the order VIBGYOR and the full form of the VIBGYOR is,

• Violet
• Indigo
• Blue
• Green
• Yellow
• Orange
• Red

Dispersion of Light happens when white light is split into its constituent hues due to refraction. Dispersion of Light can be achieved through various means but the most common way to achieve dispersion of light is through Prism. Dispersion of light by a prism results in the breaking of white light into its seven constituents.

Dispersion of Light through a prism is achieved by allowing the white light to fall on the prism and passing the light through the prism to break it into its constituent colours. In this article, we will learn about the Dispersion of Light, its experiment and others in detail.
