Question

State the sign convention of u,v and f for a concave mirror when image Is real

Answer 1

Answer:

Sign conventions

Distances measured on the other side are negative. f, the focal length, is positive for a concave mirror, and negative for a convex mirror. When the image distance is positive, the image is on the same side of the mirror as the object, and it is real and inverted.

Answer 2

Answer:

f=negative

u=always negative

v=negative (real images)

   positive (virtual images) - last case
