reflective it is coated with a layer of SiO (n=2). Find the minimum
thickness of the SiO coating to provide strong reflection for 570
nm light at normal incidence.

The block of glass (n = 1.5) shown in cross section in Figure 1
is surrounded by air. A ray of light enters the block at its
left-hand face with incident angle θ1 and reemerges into the air
from the right-hand face directed parallel to the block's base.
Determine the angle θ1.
Suppose we coat a glass window (n = 1.5) with a thin coating in
order to eliminate the reflection for normal incidence radiation,
at a wavelength of 550 nm. Find the reflectance as a function of
wavelength.
White light is shone on a very thin layer of glass (n = 1.5),
and above the glass layer, interference maxima for two wavelengths
(and no other in between) are seen: one green wavelength of 550 nm,
and one orange wavelength of 610 nm. What is the thickness of the
glass layer?
a. 1862 nm
b.1859 nm
c. 1860 nm
d.1861 nm
A study is conducted regarding shatterproof glass used in
automobiles. Twenty-six glass panes are coated with an
anti-shattering film. Then a 5-pound metal ball is fired at 70mph
at each pane. Five of the panes shatter. We wish to determine
whether, in the population of all such panes, the probability the
glass shatters under these conditions is different from π= 0.2
(a) State the appropriate null and alternative hypotheses.
(b) Check the conditions for trusting the conclusion of the
test,...
A glass window of index of refraction 1.3 is coated with an

to be suppressed?
A. 1.1 B. 1.2 C. 1.4 D. 1.7 E. 1.8
