Review L#50-57: Mon 28 Mar

Test 50 -57 on Tues 29 Mar

For the following 3 problems, use ray diagram to

find image's:

 a) location (Real or Virtual) of image

b) distance image is to mirror

c) orientation (upright or inverted)

d) height of image

e) magnification of image

Problem: 1   Concave Mirror:

 c = 6 cm

Obj's height = 4.0 cm

Obj's distance to mirror = 10 cm

Problem: 2   Concave Mirror:

 c = 14 cm

Obj's height = 3.0 cm

Obj's distance to mirror = 4 cm

Problem: 3   Concave Mirror:

 f = 6 cm

Obj's height = 4.0 cm

Obj's distance to mirror = 2 cm
