(d) A convex mirror always gives a virtual and erect image of smaller size of the object placed in front of it. Similarly, a plane mirror will always give a...
Here, in case of concave mirror
u=10 cm [u, is always negative]
v =?;m = - 3 [real image]
Now the magnification formula is
m= -v/u or -3= -(v/-10)
or , v = -30 cm.
Image will...
The image formed by a concave mirror is virtual, erect and larger only when the object is placed between the pole of the mirror and its principal focus. So correct...
A plane mirror forms an erect image of equal size; while a convex mirror forms an erect image of smaller size irrespective of the distance of object from the mirror,...
