Questions
A glass slab of thickness t = 3 cm, R.I. is placed between the object O and the concave mirror of focal length f = 4.5 cm. It is observed that the image is formed at the object. If we withdraw the slab, the image will be formed at a distance of
detailed solution
Correct option is D
Apparent shift =31-23 cm=1 cm. Therefore x-1=2×4.5⇒x=10 cm.Therefore1v−110=−29 ⇒v=9011 cmTalk to our academic expert!
