chp 22 q12

The magnification of a convex mirror is +0.53 times for objects 6.9 mm from the mirror.

Part A

What is the focal length of this mirror?

Solutions

Expert Solution

Let 'X' be the object distance from mirror

According to magnification formula.m=-v/u....................................1

Where u is the object distance and v is the image distance

We have Mirror formula

..................................................................2

where f is the focal length

-----------------------------------------3

put equation 1 in 3 gives

given  m=0.53 x

focal length of mirror is

The rearview mirror of a car is a convex mirror (R = -15 m). Consider the image formed by a car that is 10 m from the mirror. A convex mirror means that the mirror has a _positive/ negative_ radius of curvature. So, the center of curvature and focal length are located on the _same/ opposite_ side of the mirror as the incident and reflected (outgoing) light. For a mirror, the focal length is equal to __________ of the radius...
