Homework #6 complete by Wednesday, September 23

1. Fill in the following table. Each row refers to a combination of an object and either a plane mirror, a spherical concave mirror, or a spherical convex mirror. Distances are in cm. If a number lacks a sign, find the sign. Sketch a ray diagram for each combination, showing enough rays to locate the image.
Type  d2  d1  Real?  Inverted? 
a. Concave  20      +10      
b.         +10  +1.0  No   
c.  +20      +30      
d.        +60 -0.5     
e.    -40 -10         
f.  20        +0.1    
g. Convex    40 4.0        
h.        +24 0.5    Yes 

2. Fill in the following table. Each row refers to a combination of an object and a converging (C) or diverging (D) thin lens. You may not be able to determine every number in the table. Distances are in cm. If a number lacks a sign, find the sign (except for the index of refraction). Sketch a ray diagram for each combination, showing enough rays to locate the image.
Type  R1 R2 d1  d2  n  m Real?  Inverted? 
a. C   10      +20             
b.   +10     +5.0          
c.    10      +5.0     >1.0 (find #)    
d.   10     +5.0     < 1.0 (find #)    
e.    +30 -30        +10    1.5      
f.    -30 +30  +10     1.5      
g.    -30 -60   +10       1.5      
h.        +10               0.50   No
i.       +10      -0.50    

3. The disk of the Sun subtends an angle of 0.533 degree at the Earth. What are the position and diameter of the solar image formed by a concave spherical mirror with a radius of curvature of 3.00m?
