Question

A) Describe the three rules when drawing a ray diargmam for how light passes from an object thorough a lens to form an image. B)What is the minimum number of rays needed to determine the size and position of an image?

Answer #1

While drawing a ray diagram we these rules are follow:

1) Any incident ray traveling parallel to the principal axis of a converging lens will refract through the lens and travel through the focal point on the opposite side of the lens as shown in figure (A)

2) Any incident ray traveling through focal point on the way to the lens will refract through the lens and travel parallel to the principal axis as shown in figure (B)

3) An incident ray that passes through center of the lens will in effect continue in the same direction that it had when it entered the lens as shown in figure (C)

Part(b)

We need minimum two rays to determine the size and position of image as shown in position (D)

A light ray in air, indicated by the arrow, is incident on a
convex glass lens at an angle of 31° to the normal. a) Some of the
light will be reflected from the lens. At what angle will it be
reflected? b) Find the angle at which the light ray is refracted
when entering the lens. (5 points) c) Find the angle at which the
ray is incident on the other side of the lens and the angle of...

The drawing shows a ray of light traveling through three
materials whose surfaces are parallel to each other. The refracted
rays (but not the reflected rays) are shown as the light passes
through each material. A ray of light strikes the a–b interface at
a 50.0? angle of incidence. The index of refraction of material a
is na = 1.20. The angles of refraction in materials b and c are,
respectively, 42.6? and 58.7?. Find the indices of refraction in...

question 3: Use the lens maker's equation to determine the
position of an object if the
image formed by a thin convex lens is 66.7cm from the center of
the lens (next to
opposite of the object). The lens has a focal length of 40cm.

6. A ray of light travels from a transparent material to air.
The beam is refracted at an angle of 25º to the normal. The beam
travels at a speed of 2.20 x 108 m/s in the material. Determine the
angle of incidence.

1. A ray of sunlight is passing from diamond into crown glass;
the angle of incidence is 35.00°. The indices of refraction for the
blue and red components of the ray are: blue
(ndiamond = 2.444, ncrown
glass = 1.531), and red (ndiamond =
2.410, ncrown glass = 1.520). Determine the
angle between the refracted blue and red rays in the crown
glass.

focal length...

6.) A light ray traveling in air, n = 1.0, is incident (angle of
incidence = 45 o ) upon a boundary with another medium,
n = 1.2, therefore, the light ray transmitted into the second
medium is refracted as follows;
a.) transmission angle is less than 45
o
b.) transmission angle is equal to 45
o
c.) transmission angle is greater than 45
o
d.) transmission angle is unknowable
