A spherical mirror is that mirror whose reflecting surface is the part of a hollow sphere of glass. Spherical mirrors are of two types: concave and convex mirrors.

A mirror image is the result of light rays bounding off a reflective surface. Reflection and refraction are the two main aspects of geometric optics.

Answer: (d) the mirror is convex, but the lens is concave. Question 5: No matter how far you stand from a mirror, your image appears erect. The mirror is likely to be ...

In case of a concave mirror, the size of image and object will be same if the object is placed at 2f. Hence, in this case object must be place at 2 f or 2 × 15 = 30 cm.

On the other hand, convex mirrors are thinner in the middle and bend light outward. Drivers use convex mirrors in their side mirrors. By the way, your reflection in a mirror only appears to be ...
