Study Notes

Lens Maker's Formula

Lens Maker's Formula: μ1 / μ2 = (R1 + R2) / (R1 - R2)
μ1 and μ2 are the refractive indices of the lens and the outer medium respectively
R1 and R2 are the radii of curvature of the two surfaces of the lens

Refraction through a Prism

Refraction through a prism can be described using Snell's law

Thin Lens in Air

The lens equation for a thin lens in air is 1 / u + 1 / v = 1 / f
u is the object distance, v is the image distance, and f is the focal length of the lens
The magnification of a thin lens is given by M = -v / u

Refraction at a Convex Spherical Surface

The equation for refraction at a convex spherical surface is μ1 / μ2 = (R + u) / (R - v)
μ1 and μ2 are the refractive indices of the two media
R is the radius of curvature of the surface
u is the object distance and v is the image distance

Magnifying Power of a Simple Microscope

The magnifying power of a simple microscope is given by M = (25 / u) (1 + (25 / f))
u is the object distance and f is the focal length of the lens

Compound Microscope

The magnifying power of a compound microscope is given by M = M1 * M2
M1 and M2 are the magnifications of the objective and eyepiece lenses respectively

Astronomical Telescope

The magnifying power of an astronomical telescope is given by M = f_o / f_e
f_o is the focal length of the objective lens and f_e is the focal length of the eyepiece lens
