Sign conventions To figure out what the signs mean, take the side of the mirror where the object is to be the positive side. Any distances measured on that side are positive.

Is V negative in concave mirror?

For a concave mirror, it depends for all other cases except when the object is between focus and pole where it forms a virtual, erect image sign of v is negative. For: object between focus and pole, v is positive. else, v is negative.

In which mirror image is always erect?

Convex mirror

Which mirror is different?

Convex mirror is also known as a diverging mirror as this mirror diverges light when they strike on its reflecting surface. Virtual, erect and diminished images are always formed with convex mirrors, irrespective of the distance between the object and the mirror.

What are 3 types of mirrors?
