FAQs on Understanding Dispersion of Light Video Lecture - Science Class 8
| 1. What is dispersion of light? |  |
Ans. Dispersion of light refers to the phenomenon in which white light is separated into its component colors when it passes through a medium. This occurs because different colors of light have different wavelengths and thus refract at different angles.
| 2. How does dispersion occur? | |
Ans. Dispersion occurs when white light passes through a prism or a medium with varying refractive indices. The different colors of light have different wavelengths, and as they enter the medium, they experience different amounts of refraction, causing them to separate and form a spectrum.
| 3. What is a spectrum? | |
Ans. A spectrum is a range of colors that are produced when white light is dispersed. It consists of the colors of the rainbow, namely red, orange, yellow, green, blue, indigo, and violet. Each color corresponds to a specific wavelength of light.
| 4. What is the role of a prism in dispersion? | |
Ans. A prism is commonly used to demonstrate the dispersion of light. When a beam of white light enters a prism, it undergoes refraction at the prism's surfaces. The different colors of light refract at different angles, causing them to separate and form a spectrum.
| 5. What are some practical applications of dispersion of light? | |
Ans. The dispersion of light has several practical applications. It is utilized in optical instruments such as spectrometers, which analyze the composition of substances based on their absorption or emission spectra. It also plays a crucial role in photography, where different lens coatings are used to minimize chromatic aberration caused by dispersion. Additionally, fiber optics, which transmit data using light signals, rely on the dispersion properties of different wavelengths to carry information efficiently.
