The focal length of a concave mirror is 30 cm. If an object is placed 40 cm away from the mirror. Calculate the position and magnification of the image.

Answer :

Given


The distance of the object from the mirror (u) = - 40cm (as the object is on the left side of mirror and acc. To our sign convention)


The focal length of the mirror (f) = -30 cm (Focal length is negative in case of the concave mirror.)


Image distance (v) = ?


Magnification (m) = ?


Formula Used




Using mirror formula



V = -120 (same side of mirror)


The image is real.


Magnification = = -3


Hence, the image is 3 times the object and image is inverted.
