Question

When viewed in a spherical mirror, the image of a setting sun is a virtual image. The image lies 16 cm behind the mirror. (a) What is the focal length of the mirror? (b) What is the radius of curvature of the mirror?

Answer #1

A convex spherical mirror with a radius of curvature of 50 cm
generates a virtual image 16.67 cm behind the mirror. Where is the
object located?
0.3 m from the mirror
0.2 m from the mirror
0.5 m from the mirror
- 0.5 m from the mirror
none of the above

a) Locate the image of a paper clip 100 cm from a convex
spherical mirror with a radius of curvature of 80 cm. b) A concave
spherical mirror forms the image of a rose on a screen 100 cm away.
If the rose is 25 cm from the mirror, determine its radius of
curvature c) Suppose you have a concave spherical mirror with a
focal length of 10 cm. At what distance should an object be placed
if its image...

A concave spherical mirror has a radius of curvature of 18.0 cm.
Locate the image for each of the following object distances. (Enter
0 for M and the distance if no image is formed.)
(a) do = 36.0 cm
M=_____, _____cm
(b) do = 18.0 cm
M=_____, ______cm
(c) do = 9.0 cm
M=_____, _____cm
For a,b,c name each orientation (choices are
below):
in front of the mirror, real, and upright
in front of the mirror, real and inverted
behind...

When an object is placed 200 cm in front of a certain spherical
mirror, its image forms x cm in front of the mirror. If the object
is moved 80 cm closer to the mirror, its image is now x + 10 cm in
front of the mirror. Calculate the value of x, the focal length f
of the mirror, its radius of curvature R, and state whether the
mirror is convex or concave.?

When an object is placed 27 cm in front of a spherical mirror
the magnification is -0.75. What are (a) image distance (including
sign), (b) the focal length (including sign, and (c) the radius of
curvature of the mirror (including sign)?

You are given a spherical mirror and wish to determine its
properties. You place an object on its axis, 33.3 cm in front of
it, and discover that the mirror creates a virtual image located
10.9 cm from the mirror. Find the mirror's focal length.
focal length: ______cm
Calculate the mirror's radius of curvature.
radius of curvature: _____cm
If it can be determined, is the mirror concave or convex?
a.) convex
b.) cannot be determined
c.) concave

(part 1) A virtual image of a beetle is formed

convex or concave.
A. 11.3 cm; Concave
B. 3.2 cm; Convex
C. 3.2 cm; Concave
D. 11.3 cm; Convex

1.The spherical side mirror on a car is convex and has a
radius of curvature of 24 cm. Another
car is following, 2.0 m behind the mirror. If the height of
the car is 1.5 m, how tall is its image?
2. An object 5.0 cm in height is placed 7.0 cm in front of a
concave spherical mirror with a focal
length of 10.0 cm. What is the position of its image in
relation to the mirror, and what...
