Question

A spherical mirror is polished on both sides. When the concave side is used as a mirror, the magnification is +3.4. What is the magnification when the convex side is used as a mirror, the object remaining the same distance from the mirror? If the object is inverted, then enter a negative number. Otherwise, enter a positive number. A spherical mirror is polished on both sides. When the concave side is used as a mirror, the magnification is +3.4. What is the magnification when the convex side is used as a mirror, the object remaining the same distance from the mirror? If the object is inverted, then enter a negative number. Otherwise, enter a positive number.

Explanation / Answer

  

As we know that , using Formula

1/Mconcave + 1/Mconvex = 2

Therefore

1/3.4+ 1/Mconvex = 2

Mconvex = 0.58620
