Spherical Reflection (9, 4)
Equations:
1 | + | 1 | = | 1 | f = | 1 | ⋅ r | m = | –v |
-- | v-- | --f | 2-- | -----u |
u | | | | | |
Example:
Given: u=10_cm, v=300_cm, r=19.35_cm.
Solution: m=-30, f=9.6774_cm.
Spherical Refraction (9, 5)
Equation:
n1 | + | n2 | = | n2 – n1 |
----- | -----v | ------------------r |
u | | |
Example:
Given: u=8_cm, v=12_cm, r=2_cm, n1=1.
Solution: n2=1.5000.
