Question

a
ray of light strikes a flat surface separating two glasses if the
refractive index of the first glass is n = 1.92 and the second is n
= 1.52 and the angle of the incident beam is 30 degrees. calculate
the angle of refraction

a. 39.16 degrees

b. 30 degrees

c. 29.16 degrees

d. 35 degrees

Answer #1

given,

n1 = 1.92

n2 = 1.52

from snell's law

n1sin = n2sin

1.92sin30 = 1.52sin

0.96 = 1.52sin

sin = 0.96/1.52 = 0.6315

= angle of refraction = sin^-1(0.6315) = ...............Answer.

option a is correct.

hope this helps you.

please thumbs up.

A ray of light strikes a flat block of glass (n = 1.75) of
thickness 1.00 cm at an angle of 45.0° with the normal. Trace the
light beam through the glass and find the angles of incidence and
refraction at each surface.

Refraction through flat glass. Light travelling in air strikes a

as shown. If the index of refraction of the glass is 1.50, (a) what
is the angle of refraction θA in the glass; (b) what is the angle
θB at which the ray emerges from the glass?

cm is shown. The ray travels down and to the right and is incident
to the top of the block at an angle θ1 to the normal of the
surface. The ray inside the...

An aquarium filled with water (nn = 1.33) has flat glass sides
whose index of refraction is 1.52. A beam of light from outside the
aquarium strikes the glass at a 43.5∘∘ angle to the perpendicular
(Figure 1).
Part A: What is the angle of this light ray when it enters the
glass?
Part B; What is the angle of this light ray when it enters the
water?
Part C: What would be the refracted angle if the ray entered...

A plate of glass with parallel faces having a refractive index
of 1.52 is resting on the surface of water in a tank. A ray of
light coming from above in air makes an angle of incidence 34.0 ∘
with the normal to the top surface of the glass.
What angle θ3 does the ray refracted into the water make with
the normal to the surface? Use 1.33 for the index of refraction of
water.

A light ray strikes a flat, L = 4.4 cm thick block of glass (n =
1.5)in the figure below at an angle of
θ = 33° with the normal.
Find the angles of incidence and refraction at each surface.
I need the the incidence top and refraction/ bottom . Got the
other two, and can you show how you get them?

A monochromatic ray of light enters a flat piece of glass (index
of refraction = n) from air (index of refraction n = 1). The ray
passes through the glass and re-enters the air through the bottom
surface of the glass sheet. The angle it makes with the normal when
it has re-entered the air is
a.
the same as the angle it made with the normal when it was
originally in air.
b.
the same as the angle it...

A block of crown glass of refractive index 1.52, is immersed in
water of refractive index 1.33, as in the figure shown below. A
light ray is incident on the top face at an angle of
θ1 = 42.2° with the normal and exits the block
at point P. (Assume that x = 3.63 cm.)
A block is immersed in water. A ray starts in the water at the
top of the image and moves down and to the right...

1) The refractive index of a transparent material can be
determined by measuring the critical angle when the solid is in
air. If ?c= 41.5° what is the index of refraction of the
material?
2) A light ray strikes this material (from air) at an angle of
36.9° with respect to the normal of the surface. Calculate the
angle of the reflected ray (in degrees).
I know this one is 36.9 degrees.
3) Calculate the angle of the refracted ray...

Use the exact values you enter to make later calculations.
