An object of height h is in front of a spherical mirror which
has a focal length of abs( f ) = 30 cm. The image of this object
has the same orientation as the object, and has height h' = 0.25 h.
What is true?
a) In front of spherical concave mirror of radius 26cm, you
position an object of height 2.6cm somewhere along the principal
axis. The result image has a height of 0.8cm. How far from the
mirror is the object located?
b) In front of a spherical convex mirror of radius 26cm, you
position an object of height 2.6cm somewhere already no the
principal axis. The resultant image has a height of 0.8cm. How far
from the mirror is the object located?...
A object of height 3.3 cm is placed 36.1 cm in front of a
spherical mirror. Suppose it is desirable to produce a virtual
image that is upright and 1.4 cm tall.
(a) Should a concave or convex mirror be used?
b) Where is the image located?
c) What is the focal length of the mirror?
d) What is the radius of curvature of the spherical mirror?
1. Please complete the following parts of the question regarding optics.
a) A 4.0 cm -tall object is 15 cm in front of a CONVEX mirror that has a -25 cm focal length. Calculate the image position then Calculate the image height. Type a positive value if the image is upright and a negative value if it is inverted.
b) A 3.0-cm-tall object is 17 cm in front of a CONVERGING lens that has a 32 cm focal length....
An object is placed 31.5 cm from a +5.0-D lens. A spherical
mirror with focal length 25 cm is placed 75 cm behind the lens.
Note that the mirror reflects light back through the lens.
Find the distance from original object to the final image,
measured from the object toward the lens. Enter negative value if
the object is between the image and the mirror and positive value
otherwise.
An object 5.8 cm in height is placed 7.3 cm in front of a
concave spherical mirror with a focal length of 10.8 cm. What is
the position of its image in relation to the mirror, and what are
the characteristics of the image?
1. If a concave mirror has a focal length of 20 cm, at which
object distance will an image larger than objects be formed on
screen?
a.) 40 cm b.) 30 cm c.) none of the choices d.) 14 cm e.) 50
cm
2. An electron and proton are projected with the same velocity
when a uniform magnetic field perpendicular to the velocity of the
two charges is applied. The electron follows a circular path of
radius 1 mm. What...
A concave spherical mirror with a focal length of 12 cm faces a
plane mirror with the optical axis of the spherical mirror
perpendicular to the plane mirror. A small object is placed at
point P on the optical axis, 11 cm from the plane mirror and 29 cm
from the vertex of the spherical mirror. Find the distance from the
plane mirror to the three nearest images. (Enter your answers from
smallest to largest.)

For a convex mirror, when the object is 24.2 cm in front of the
mirror the image is 15.4 cm behind the mirror. If the object is
moved to a distance of 14.5 cm in front of the mirror, determine
the distance of the image behind the mirror (cm)
A concave mirror has a focal length of 43.8 cm. The distance
between an object and its image is 76.6 cm. Find (a) the object and
(b) image distances, assuming that the object lies beyond the
center of curvature and (c) the object and (d) image distances,
assuming that the object lies between the focal point and the
mirror.
A concave mirror has a focal length of 32.2 cm. The distance
between an object and its image is 54.7 cm. Find
(a) the object and (b) image
distances, assuming that the object lies beyond the center of
curvature and (c) the object and
(d) image distances, assuming that the object lies
between the focal point and the mirror.
