HP 48gII Graphing Spherical Reflection 9, Spherical Refraction 9, Thin Lens 9, Solution n2=1.5000

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.

Thin Lens (9, 6)

r1 is for the front surface, and r2 is for the back surface.
