FAQs on Spherical Mirrors Video Lecture - Physics Class 12 - NEET

 1. What is a spherical mirror?
Ans. A spherical mirror is a reflective surface that is curved like a portion of a sphere. It can either be a concave mirror, which curves inward like the inside of a bowl, or a convex mirror, which curves outward like the outside of a ball.
 2. How does a concave mirror work?
Ans. A concave mirror works by reflecting light rays that are parallel to its principal axis and passing through its focal point. The reflected rays converge at the focal point, resulting in an image that can be real or virtual, depending on the position of the object.
 3. What is the difference between a real and virtual image produced by a concave mirror?
Ans. A real image is formed when the reflected rays of light actually converge at a point in space. It can be captured on a screen and is always inverted. On the other hand, a virtual image is formed when the reflected rays appear to diverge from a point behind the mirror. It cannot be captured on a screen and can be either upright or inverted.
 4. How does a convex mirror work?
Ans. A convex mirror works by reflecting light rays that strike its surface. The reflected rays diverge and appear to originate from a point behind the mirror. This causes the image formed by a convex mirror to be smaller, upright, and virtual.
 5. What are some practical applications of spherical mirrors?
Ans. Spherical mirrors have various practical applications. Concave mirrors are used in telescopes, satellite dishes, and makeup mirrors to produce enlarged and magnified images. Convex mirrors are commonly used as rear-view mirrors in vehicles, allowing drivers to have a wider field of view. They are also used in security mirrors to provide a wide-angle view in areas with blind spots.
