Question

What is a ray diagram? What is the minimum number of rays needed to draw a ray diagram. In your answer be sure to address the following for concave and convex mirrors:

a) What happens to rays that are parallel to the principle axis and are reflected at the mirrors surface?

b) What happens to rays that travel on trajectories that would take them through the focal point?

c) What happens to rays that travel on trajectories that would take them through the radius of curvature?

Answer #1

Draw a ray diagram for a convex mirror
Drag a ray diagram
P( object distance )= 30
Q( image distance )= 56
F( focal length )=19.5
R( radius of curvature= 39

Convex mirrors allow for a wide view, which is why they are used
as security mirrors in stores.
(a) Draw the ray diagram for an object being reflected in a
convex mirror. Use the ray through the centerline and the ray that
comes parallel to the mirror.
(b) The books goes through the proof of the relationship between
a source location, s, the image location, i, and the focal length,
f, given by:
1/s + 1/s' = 1/f .

A concave spherical mirror has a radius of curvature of 30 cm.
Draw separate ray diagrams to locate the images (use central,
focal, and parallel rays and use a ruler) for objects at:
a) 45 cm and
b) 10 cm from the mirror. State whether each image is real or
virtual, inverted or not, and enlarged or reduced.
c) Use the mirror equation to locate and describe part (a).
d) Do the same for part (b).

Rays pass through a semi-circular, plano-convex lens with a
radius of curvature of 7.62 cm. As light rays incident on the flat
side of the lens and exit through the circular side, a ray incident
along a line parallel to the axis of the lens is 2.00 cm above or
below that axis would converge to a focus 18.90 cm from the
geometric center of the lens. What is the effective index of
refraction for the material the lens is...

A woman at a carnival funhouse is standing between a convex
mirror and a concave mirror which are 3.00 m apart. The woman is
2.00 m from the convex mirror. The radius of curvature of the
convex mirror is 2.00m. An upright image formed in one of the
mirrors is reflected by the other mirror, making a final image at
the position of the original woman. The woman is 1.70 m tall. (a)
Do two separate ray tracing diagrams, showing...

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...

Problem As the resident physics expert, you’ve been called in to
take care of some hornets that have been terrorizing your dorm. You
find their nest is located high up in a tree. Your flamethrower is
on backorder, so you’ll have to find another way to burn them out.
In the deep recesses of the physics and astronomy basement, you
find a very large concave spherical mirror from an old telescope.
The mirror is 2 m across with an unknown...

A 3.0 cm high object is placed 5.0 m in front of a concave
spherical mirror with radius of
curvature 2.0 m.
A) At what distance from the mirror is the image formed?
B) What is the magnification?
C) How high is the image?
D) Is the image upright or inverted? Is the image real or
virtual?
E) Draw a ray diagram for the image formed for the same object
at the same location by the
aforementioned mirror. Also, check...

How does light travel in a fibre optic cable? Draw the path of a
light ray having an angle of incidence of 75 degrees on an optical
fibre with index of refraction n2=1.5 and where air is the external
medium or n1=1.
Can light ever leave the cable? What would happen if the cable
were to be bent?
What happens when a laser beam is passed through a prism? Is
dispersion observed?
What does it mean to say light is...

A photographer wishes to photograph a 20m tall tree from a
distance of 30m. He wishes to fill the 20mm size sensor array in
his camera with the image. 1. What kind if lens must he use
(concave/convex)? And what kind of image must be formed on the
sensor (real/virtual)? Is the image upright or inverted? (3
Points)
2. Draw a clearly labeled ray -diagram showing image formation
in this case. Label the principal axis, the focus, and the object...
