# Numerical Problems From Optics

When an object of height 4cm is placed at 40cm from a mirror the mirror forms the image on the object itself. If the height of the image is equal to the height of the object. Find out the focal length of the mirror and identify the mirror. A convergent beam of light passes through … Continue reading Numerical Problems From Optics
