An object is placed in front of a convex mirror of radius of curvature 40cm at a distance of 10cm. Find the position nature and magnification of mirror. |
|
Answer» SOLUTION :u=-10cm R=-40cm Then f=R/2=-20cm From the mirror formula 1/v=1/f-1/u -1/20+1/10=1/20 V=20cm so v is POSITIVE Hence a virtual and erect IMAGE will be FORMED on the other side of the object, i.e BEHIND the mirror. M=-v/u=-20/-10=2 Magnification of mirror is 2 |
