FAQs on Dispersion(Splitting) of Light through Prism Video Lecture - Science Class 7 (Old NCERT)
| 1. What is the phenomenon of dispersion of light through a prism? |  |
Ans.Dispersion of light through a prism refers to the process by which white light is separated into its constituent colors when it passes through a transparent material, like glass. This occurs because different colors of light have different wavelengths and refract at slightly different angles when entering and exiting the prism. The result is a spectrum of colors, typically seen as red, orange, yellow, green, blue, indigo, and violet.
| 2. How does a prism cause the splitting of light? | |
Ans.A prism causes the splitting of light by utilizing the principle of refraction. When light enters the prism, it slows down and bends due to the change in medium from air to glass. Each color of light bends at a different angle because of its unique wavelength. As a result, when the light exits the prism, the colors spread out and form a visible spectrum.
| 3. Why do different colors of light bend at different angles when passing through a prism? | |
Ans.Different colors of light bend at different angles due to their varying wavelengths and the refractive index of the prism material. Shorter wavelengths (like violet) refract more than longer wavelengths (like red) when they pass through the prism. This differential bending is what leads to the separation of colors, creating a spectrum.
| 4. What are the main colors observed in the spectrum produced by a prism? | |
Ans.The main colors observed in the spectrum produced by a prism are red, orange, yellow, green, blue, indigo, and violet. These colors can be remembered using the acronym ROYGBIV, which represents the sequence of colors from longest wavelength (red) to shortest wavelength (violet).
| 5. Can the dispersion of light through a prism be observed with other light sources besides sunlight? | |
Ans.Yes, the dispersion of light through a prism can be observed with other light sources, such as incandescent bulbs or LED lights. However, the quality and range of the spectrum may vary depending on the light source. For example, a white incandescent bulb will produce a spectrum similar to sunlight, while colored lights may only show limited colors based on their specific wavelengths.
