An
insect is embedded inside a glass block( n=1.4) so that it is
located 3.8cm below a plane surface of the block. how far from this
surface does this insect appear to a person looking at the
block?
Solutions
Expert Solution
Here, n = refractive index
t =
original depth
far from this surface does this insect appear to a person = t(1
- 1/n)
A thin film of oil (n = 1.4) of thickness 1.4micrometers. is
compressed between two glass slabs (n = 1.5).
White light containing wavelengths from 400 to 700nm (measured in
air) is incident normally on the film.
In the reflected light, which wavelengths (from long to short)are
a) missing (4 of them) and b) enhanced (4 of them)
A ray of light traveling in a block of
glass
(n=1.52) is incident on the top
surface at an angle of 57.4?
with respect to the normal in the glass. If a
layer of oil is placed on the top surface of the glass, the ray is
totally reflected.
What is the maximum possible index of
refraction of the oil?
a glass tube both ends are open is dipped inside mercury so that
one half is above the mercury level. then the one half of open end
is closed and taken out there with a
10 cm long mercury left. if atmospheric pressure is 76cnHG
calculate the length of the tube
answer is 16 cm pls explain the answer
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.
