Define convex mirror and concave lenses
Answers
Answer:
- A convex mirror or diverging mirror is a curved mirror in which the reflective surface bulges towards the light source.
- A lens having at least one surface curved like the inner surface of a sphere is called concave lenses.
Answer:
CONVEX MIRROR:
A curved mirror is a mirror with a curved reflecting surface. The surface may be either convex or concave. Most curved mirrors have surfaces that are shaped like part of a sphere, but other shapes are sometimes used in optical devices.
CONCAVE LENS:
A concave lens is a type of lens that diverges a straight light beam coming from the source to a diminished, upright, virtual image is known as a concave lens. It can form both real and virtual images. Concave lenses have at least one surface curved inside. A concave lens is also known as a diverging lens because they are shaped round inwards at the center and bulges outwards through the edges, making the light diverge on it. They are used for the treatment of myopia as they make faraway objects look smaller than they really are.
