Question

A convex mirror has a focal length of -10.8 cm. An object is placed 32.7 cm from the mirror's surface. Determine the image distance.

Answer 1

Answer:

Explanation:

For this question, we need to use the mirror formula

1

f

=

1

d

o

+

1

d

i

.

What the problem gives us is: f = 10.0 cm, and

d

i

= +30.0 cm. We know that

d

i

is positive because it forms a real image. So we are solving for

d

o

. Isolating the unknown to its own side of the equation, in this case by subtracting

1

d

i

from both sides, will accomplish this

Answer 2

Answer:

virtual

The image produced by a convex mirror is always virtual, and located behind the mirror. When the object is far away from the mirror the image is upright and located at the focal point.
