Question

The
In concave mirror creet is formed
only when the object is placed
between hole and fours so object
distance should be less than 12m
than
the object.
If the object distance is 24cm
which
is the approxe portion of cente
of curvatur then the image will be
formed
same position
be larger
image would
-9​

Answer 1

Answer:

According to sign convention , the distance of object from the pole of lens is negative (−u) and given that u>R.

Now by

u

1

+

v

1

=

R

2

or v=

2u−R

uR

but u>R it means that v will be negative (when we put the signs of u and R ) and v<R. v will have a value between R and R/2 .

Now magnification m=−

u

v

=<−1 (because v<R and u>R)

it means inverted and smaller image

As v is negative ,a real ,inverted and smaller image of the object will be formed between focus (R/2) and R.
