Question

An object of 3cm height is placed 60 cm in front of a concave mirror of focal length 30 cm . Find the nature ,position and size of the image.

Answer 1

we should calulate the image distance

by using sign convention

1/-30=1/-60+x

1/-30+1/60=x

X=1/60

v=60

magnification formulae=-v/u

-60/60=-1

therefore the image will be same size,inverted,real image
