A spherical concave shaving mirror has a radius of curvature
A spherical, concave shaving mirror has a radius of curvature of 35.0 cm .
Part A
What is the magnification of a person\'s face when it is 10.5 cm to the left of the vertex of the mirror?
Part B
Where is the image?
The picture is
Where is the image?
of the mirror.
Part C
Is the image real or virtual?
| 10.5 cm to the left | |
| 10.5 cm to the right | |
| 26.3 cm to the right | |
| 26.3 cm to the left | |
| 100.0 cm to the right | 
Solution
a)
m = -v/u
m = 26.25/10.5 = 2.5
b)
f = -35/2 = -17.5cm
1/v + 1/u = 1/f
u = -10.5 cm
v = 1/(-1/17.5 +1/10.5)
v = 26.25 cm to the right
c)
virtual
