(Optical Fiber)
A typical optical fiber has a
cylindrical core with an index of refraction of 1.62 wrapped by a cladding jacket
whose index of refraction is 1.52. The diameter of the core is 50 m (microns).
Light traveling in air is launched into one end
(Compound Microscope)
Design a compound microscope with a total magnifying power of 500x. The
distance between the objective and eyepiece lenses must be between 12 cm and 16
cm.
Tell me your design by specifying the following quantities:
total magnificati
(Designing Lenses II)
A lens with an index of refraction of 1.61 has a front surface with an radius of
curvature of 14 cm.
(a) Find the radius of curvature of the second surface if the lens is to act as a
positive lens with a focal length of 12 cm. Sketch
. (Apparent Depth and Paraxial/Nonparaxial Rays)
A fish is resting one meter below the surface in a pool of water (n = 1.33). Find the
depth of the fishs image below the surface if the image is viewed with rays that
strike the water-air interface at an an
(Blackbody Radiation & You)
You are sitting in your room doing physics homework. Your skin temperature is
95F (a typical skin temperature). Let's say that your skin surface area is 12000
cm2 and that you radiate as a perfect blackbody.
(a) At what wavelen
Antireflection Coatings)
Magnesium fluoride (n = 1.38) is often used as an antireflecting coating on lenses.
Find the minimum thickness necessary to use on a glass lens with n = 1.5 so that
the loss of light due to reflection is minimized. Since white lig
(Isotopes of Hydrogen)
The three isotopes of hydrogen are commonly called hydrogen (1H), deuterium
(2H), and tritium (3H). Hydrogen and deuterium are stable while tritium decays via
- emission with a half-life of 12.33 years.
(a) Find the binding energies
(Special Relativity Meets The Original Star Trek)
Captain Kirk leaves the Enterprise in a shuttlecraft and speeds away at 0.7c relative
to the Enterprise. Mr. Spock, back on board the Enterprise, monitors the
shuttlecraft with the ship's sensors.

(Bohr Model of Hydrogen)
Consider a Hydrogen atom in the ground state. Using Bohr's model, answer the
following questions.
(a) What is the minimum amount of energy necessary to ionize the atom (i.e. to
remove the electron from the atom)?
(b) What waveleng
(Relativistic Energy & Momentum)
An electron is accelerated from rest to a speed where its total energy is equal to
twice its rest energy.
(a) How much energy did it take to do this?
(b) How fast is the electron traveling?
(c) Find the momentum of the ele
