FAQs on Introduction: Plane Mirror & Spherical Mirrors Video Lecture - Crash Course: Class 10

1. What is a plane mirror?
Ans. A plane mirror is a flat mirror that reflects light rays in a predictable manner. It has a smooth and flat reflective surface, which creates a virtual image that is the same size and distance behind the mirror as the object in front of it.
2. How does a plane mirror work?
Ans. A plane mirror works by reflecting light rays that strike its surface. When light rays hit the mirror, they bounce off in a way that follows the law of reflection. The angle of incidence (the angle at which the light ray strikes the mirror) is equal to the angle of reflection (the angle at which the light ray bounces off the mirror).
3. What are the characteristics of a plane mirror?
Ans. The characteristics of a plane mirror include: - It forms a virtual image that is the same size as the object. - The image formed is laterally inverted, which means left and right are swapped. - The image distance is equal to the object distance from the mirror. - The image is located behind the mirror. - The image is erect (upright) and not inverted.
4. What are spherical mirrors?
Ans. Spherical mirrors are mirrors that have a curved shape, either convex or concave. Convex mirrors curve outward, while concave mirrors curve inward. These mirrors can form both real and virtual images, depending on the position of the object in relation to the mirror and the curvature of the mirror's surface.
5. How do spherical mirrors form images?
Ans. Spherical mirrors form images by reflecting light rays. Concave mirrors can form both real and virtual images. Real images are formed when the object is placed beyond the focal point of the mirror, and the image is formed in front of the mirror. Virtual images are formed when the object is placed between the mirror and its focal point, and the image is formed behind the mirror. Convex mirrors always form virtual, diminished, and erect images.
