Physics Light Part 9 (Spherical Mirror) Class 7 VII

## TL;DR

Spherical mirrors, such as concave and convex mirrors, have different reflective surfaces that can either form smaller or larger images of objects.

## Key Insights

• đĒŠ Spherical mirrors are derived from a reflective spherical surface, with the inner surface of a concave mirror being shiny and the outer surface of a convex mirror being shiny.
• đ The concave mirror forms an inverted image, while the convex mirror forms an erect or smaller image.
• đĨŖ Spherical mirrors, like those in a spoon, can have both concave and convex surfaces.
• đ The distance of the object from the mirror affects the type of image formed.

### Q: How do spherical mirrors form images that are smaller or larger than the object?

Spherical mirrors form images that are smaller or larger than the object depending on whether they are concave or convex. The curvature of the mirror's surface determines the image formation.

### Q: What are the applications of spherical mirrors?

Spherical mirrors have applications in rearview mirrors, where a wider view is required, and in dentistry, where magnification helps with examining teeth and gums.

### Q: How are concave and convex mirrors different?

Concave mirrors have a shiny inner surface and can form real or virtual images. Convex mirrors have a shiny outer surface and form virtual, smaller images of objects.

### Q: What determines the type of image formed by a spherical mirror?

The distance of the object from the mirror and the curvature of the mirror's surface determine the type of image formed, whether it is smaller, larger, erect, or inverted.

## Summary & Key Takeaways

• Spherical mirrors, like the rearview mirror of a car and the mirror used by dentists, produce images that can be either smaller or larger than the object.

• The reflective surface of a concave mirror is shiny on the inner side, while a convex mirror has a shiny outer surface.

• Spherical mirrors find various applications, such as providing a wider view in a rearview mirror or magnifying images for dental examinations.
