Question
Chapter 31, Problem 1ASA
To determine
The difference between the concave and convex spherical mirrors.
Expert Solution & Answer
Answer to Problem 1ASA
The convex spherical mirror shows the image that is diminished and errect whereas concave spherical mirror shows the image that is enlarged and real.
Explanation of Solution
Spherical mirror are the mirrors that has the shape of the piece cut of the spherical surface. The spherical mirror are of two types, one is the concave spherical mirror and other is the convex spherical surface.
The word concave means hollowed and rounded like the interior of the sphere. The concave spherical mirror is also called the converging mirror. In the concave mirror the coating is on the outside the spherical surface. In this the reflecting surface and the center of the curvature are on same side of the mirror.
The focus is in the front of mirror and the image that is formed by the concave mirror is real, inverted in all the cases except when the object is between the pole and focus then the image is virtual and errect. The use of these mirrors are in torch lights, reflecting telescope and in shaving mirrors.
The word convex means curved and rounded like the exterior of the sphere. . The convex spherical mirror is also called the diverging mirror. In the convex mirror the coating is done inside the spherical surface. In this the reflecting surface and the center of the curvature are on the opposite side of the mirror.
The focus is behind the mirror and the image that is formed by the convex mirror is virtual, diminished and errect The use of these mirrors are in vehicles as there are rearview mirrors that cover the wide area.
Conclusion:
Thus, the convex spherical mirror shows the image that is diminished and errect whereas concave spherical mirror shows the image that is enlarged and real.

The company is designing an electromagnetic propulsion system for a new roller coaster. A model of a substructure of the device appears in the figure below. Two parallel, horizontal rails extend from left to right, with one rail behind the other. A cylindrical rod rests on top of and perpendicular to the rails at their left ends. The distance between the rails is d and the length of the rails is L. The magnetic field vector B points vertically down, perpendicular to the rails. Within the rod, the current I flows out of the page, from the rail in the back toward the rail in the front. The rod is of length d = 1.00 m and mass m = 0.700 kg. The rod carries a current I = 100 A in the direction shown and rolls along the rails of length L = 20.0 m without slipping. The entire system of rod and rails is immersed in a uniform downward-directed magnetic field with magnitude B = 2.30 T.
