w define concave mirrors
Answers
Answer:
A curved mirror is a mirror with a curved reflecting surface. The surface may be either convex or concave. A concave mirror is a mirror that is curved inward in the middle. It might help you to remember this if you think that when you look in a concave mirror, it looks like you are looking into a cave. Light converges at a point when it strikes and reflects back from the reflecting surface of the concave mirror. Hence, it is also known as a converging mirror. When the concave mirror is placed very close to the object, a magnified and virtual image is obtained. However, if we increase the distance between the object and the mirror then the size of the image reduces and a real image is formed. So, the image formed by the concave mirror can be small or large and it can also be real or virtual.
