Question

which spherical mirror has a virtual focus convex or concave​

Answer 1

Answer:

convex

Explanation:

The type of spherical mirror whose reflecting surface is bulged outwards, in the sense that its face is opposite to the centre of the sphere is known as a convex mirror. ... The image formed by a convex mirror is a virtual image, while concave mirror forms a real or virtual image, depending on the position of the object

Answer 2

The spherical mirror which has virtual focus:

• The spherical mirror which has a virtual focus is a convex mirror.

• The concave mirror has real focus while a convex mirror has virtual focus.

• The emphasis for a convex mirror is being virtual, and it lies behind the mirror. And the focus for a concave mirror is being real and lies in front of the mirror.
