focal length of a concave mirror is 10 cm find the position nature and size of the image formed when an object is placed 10cm from the mirror
focal length of a concave mirror is 10 cm find the position nature and size of the image formed when an object is placed 10cm from the mirror

formula for finding image distance(v) is given
[tex] \frac{1}{f} = \frac{1}{v} + \frac{1}{u} [/tex]
and
[tex] \frac{1}{v} = \frac{1}{f} - \frac{1}{u} [/tex]

where,
f is focal length
v is image distance,and,
u is object distance ​​
