Question

At an intersection of hospital hallways, a convex spherical
mirror is mounted high on a wall to help people avoid collisions.
The magnitude of the mirror's radius of curvature is 0.574 m. (a)
Locate the image of a patient 10.6 m from the mirror. (Use the
correct sign conventions.)

cm (from the mirror)

(b) Indicate whether the image is upright or inverted.

upright inverted

(c) Determine the magnification of the image.

Answer #1

**Solution:-**

**Given –**

Radius of curvature – 0.574 m

A convex mirror always produces an image that is, diminished behind mirror upright virtual.

**a) ** **Focal
length f = 0.287 m (1/2 radius of curvature and
virtual)**

Object distance, u = 10.6 m

V – Image distance

1/u + 1/v = -1/0.287 m

1/v = -1/0.287 – 1/10.6

1/v = 3.3899

V = 0.294 m

**Or v = 29.4 cm (behind mirror,
virtual)**

**c) ** **Calculate
magnification**

M = -v/u

M = - (-0.294 / 10.6)

**M = 0.027 (upright
image)**

**b) ** **Answer of b
part is mentioned in a and c**

At an intersection of hospital hallways, a convex spherical
mirror is mounted high on a wall to help people avoid collisions.
The magnitude of the mirror's radius of curvature is 0.542 m.
(a) Locate the image of a patient 10.2 m from the mirror. (Use
the correct sign conventions.)
Apply the mirror equation using the correct focal length and object
distance to find the image distance. cm (from the mirror)
(b) Determine the magnification of the image.

You have a concave spherical mirror with a 12.9 cm radius of
curvature. You place an object on the mirror's axis, 17.1 cm in
front of the mirror. How far is the object's image from the mirror?
image distance: If it can be determined, is the image real or
virtual? real cannot be determined virtual If it can be determined,
is the image upright or inverted with respect to the object?
upright cannot be determined inverted

You view yourself in a large convex mirror with 2.4 m radius of

b) Determine the location of your image with respect to the
mirror’s location.
c) Determine the magnification of the convex mirror. Is the
image upright or inverted?
d) If you are 1.7 m tall, determine the height of the image.

Spherical mirrors. Object O stands on the
central axis of a spherical mirror. For this situation object
distance is ps = +24 centimeters, the type of
mirror is convex, and then the distance between the focal point and
the mirror is 40 cm (without proper sign). Find
(a) the radius of curvature r (including
sign), (b) the image distance i, and
(c) the lateral magnification m. Also,
determine whether the image is (d) real or
virtual, (e) inverted from object...
