Question

11. A fiber is placed between two flat glass plates at their
ends. When the plates of

length 14.0 cm, are illuminated from above with light of λ = 650
nm, bright

interference bands separated by 0.580 mm. What is the diameter of
the fiber? answer (78.4 um)

please draw and explain

Answer #1

Thanks you

A wedge of silicone gel (index of refraction ns = 1.45) sits on
a glass plate (with an index of refraction ng = 1.56). The length
of the plate is L = 12 cm and the maximum height of the gel is h =
0.02 mm. Light of a wavelength λ = 600 nm is incident on the gel.
6) What is the separation between the bright bands? A. 1.45 mm B.
1.24 mm C. 2.61 mm D. 1.80 mm...

Need the correct answer and show me the steps how to
solve it.
--The glass plates (n=1.5) are separated by a thin round
filament. When the top plate is illuminated with light having a
wavelength of 550nm. It is observed that the filament lies directly
below the sixth bright fringe. The diameter of the filament is
a. 1650 b.
1788
c.1238
d. 1375 e.
1512
--The fake “diamond” polarizing angle 62.97 degree, what is the
stone?
a. n=1.560 b.

QUESTION 10
A student took a laser with wavelength 532 nm and pointed the
beam at a fiber. The student then observed the diffraction pattern
on a paper positioned 85.4 cm past the fiber. The central maximum
of the diffraction pattern had a width of 47.8 mm. What is the
diameter of the fiber in micrometers (µm)? (State the answer in
micrometers with 2 digits right of decimal.)

Which of the following make the separation between fringes
greater in the two slit interference experiment? (Select all that
apply.)
Wider slits.Smaller separation of the two slits.Larger
separation of the two slits.Narrower slits.
PRACTICE IT
Use the worked example above to help you solve this problem. A
screen is separated from a double-slit source by 1.22 m. The
distance between the two slits is 0.0292 mm. The second-order
bright fringe (m = 2) is measured to be 4.60 cm from...

1. Light traveling in air (index of refraction 1.00) falls onto
a thin plastic film (index of refraction 1.30) of unknown thickness
that covers glass (index of refraction 1.50). What minimum non-zero
thickness is needed such that wavelengths of 650 nm in air are
bright in the reflection?
2. You observe two point sources of light that are spaced 10 cm
apart which are each emitting light of wavelength of 590 nm. If the
diameter of your pupil is 2...
