FAQs on 3 Days Timetable: Ray Optics and Optical Instruments (2025) - Physics for JEE Main & Advanced

1. What are the different types of mirrors and how do they reflect light?
Ans. The main types of mirrors are plane mirrors, concave mirrors, and convex mirrors. Plane mirrors reflect light in a way that the image is the same size as the object, and it appears reversed. Concave mirrors can converge light rays, producing magnified images when the object is close and inverted images when the object is far away. Convex mirrors, on the other hand, diverge light rays, creating smaller, upright images, which are useful for wide-angle views in vehicles.
2. What is refraction and how does it occur at spherical surfaces?
Ans. Refraction is the bending of light as it passes from one medium to another due to a change in its speed. At spherical surfaces, the amount of bending depends on the curvature of the surface and the refractive indices of the media involved. For instance, when light travels from air (lower refractive index) into glass (higher refractive index), it slows down and bends towards the normal, and vice versa when exiting the glass back into air.
3. Can you explain total internal reflection and where it occurs?
Ans. Total internal reflection occurs when light attempts to move from a denser medium to a less dense medium at an angle greater than the critical angle. This phenomenon is crucial in fiber optics as it allows light to be transmitted efficiently along the fiber without escaping. It occurs at the boundary between materials like glass and air when the angle of incidence exceeds the critical angle specific to the pair of materials.
4. What is dispersion in prisms and how does it work?
Ans. Dispersion in prisms occurs when white light is separated into its constituent colors as it passes through the prism. This happens because different colors of light have different wavelengths and refractive indices, causing them to bend at different angles. For example, violet light bends more than red light, resulting in the spread of colors known as a spectrum, which is visible when light exits the prism.
5. How do optical instruments utilize the principles of ray optics?
Ans. Optical instruments like microscopes and telescopes use the principles of ray optics to magnify images. They employ lenses that refract light rays to focus them, creating larger images of small objects (in microscopes) or distant celestial bodies (in telescopes). The design of these instruments is based on understanding how light rays behave when they pass through different media, allowing for precise control of image formation and clarity.
