Question

State the 'signs' (positive or negative) which can
be given to the following:
a) object distance for a concave mirror or a
convex mirror.
b) The image distances for a convex mirror
c) focal length of concave mirror
d) focal length of convex mirrort
e) height of real and inverted image

Answer 1

HEYA MATE!! HERE IS UR ANSWER...

a) The object distance for a concave and a convex mirror is always NEGATIVE ....this is because the object is always placed in front of the mirror..

b)The image distance for a convex mirror is always POSITIVE .....because the image formed by the convex mirror is virtual and behind the mirror..

c)The focal length of a concave mirror is always represented by a NEGATIVE SIGN...because the concave mirror has a real focus in front of the mirror..

d)The focal length of a convex mirror is represented by a POSITIVE SIGN...because it has a virtual focus behind the mirror..

e)The height of real and inverted image is denoted by a NEGATIVE SIGN....because the image formed is in front of the mirror and below the principle axis..

HOPE IT HELPED!!
