Question

A Fabry-Perot cavity is made from a 1.8 cm thick slab of germanium, with index of refraction 4.02. Find the coefficient of finesse. A Fabry-Perot cavity is made from a 1.00 cm thick slab of germanium, with index of refraction 4.02. Find the resolving power when the wavelength is 3.42 microns

Answer #1

A Fabry-Perot cavity is made from a 2.2 cm thick slab of
germanium, with index of refraction 4.02. Find the coefficient of
finesse.
A Fabry-Perot cavity is made from a 1.00 cm thick slab of
germanium, with index of refraction 4.02. Find the resolving power
when the wavelength is 3.37 microns.

Assume an air-filled Fabry-Perot interferometer made from two
similar, parallel mirrors. For a wavelength of 610nm, the fraction
of transmitted light to incident light is 0.0154. The distance of
separation is ℓ = 2.60μm. What is (a) the finesse, F, and (b) the
reflectance of the mirrors, R, when assuming only reflective
contributions to the etalon's finesse?

Q3.
(a) A tank containing methanol has walls 2.50 cm thick made of
glass of refractive index 1.540. Light from the outside air strikes
the glass at a 41.5° angle with the normal to the glass. Find the
angle the light makes with the normal in the methanol. (The index
of refraction of methanol is 1.329.)

(b) The tank is emptied and refilled with an unknown liquid. If
light incident at the same angle as in part (a) enters...

A biconvex lens is made from transparent material of refractive
index n = 1.60. The power of the lens is +1.00 diopters. If the
magnitude of the radius of one face is 12.0 cm, find the magnitude
of the radius of the other face.

An object placed 10.0 cm in front of a lens produces an image
with magnification 2/3 ( = 0.667). At what distance in front of the...

1) 2 point charges are separated by a distance of 8 cm. The left
charge is 48 mC and the right charge is -16mC. Using a full sheet
of paper: draw the 2 charges separated by 8cm, centered in the
sheet. (if you are missing a ruler estimate 8cm as ⅓ a paper sheet
length). [6] a) Draw field lines to indicate the electric fields
for this distribution. [4] b) Draw 3 equipotential surfaces, 1
each, that pass: -Through the...
