2. 1. Assume that a certain concave
spherical mirror has a focal length
of 20.0 cm. locate the image for an
object distance of 40 cm and
describe the images’
characteristics.
3. 2. Assume that a certain concave
spherical mirror has a focal length
of 3 cm. Locate the image for an
object distance of 6 cm and
describe the image’s
characteristics.
4. 3. A convex mirror has an object placed
at 15 cm in front of it. An image is
formed 20 cm from the mirror. What isa
the nature of the image? Calculate the
magnification of the image and the
focal length of the mirror.
5. 4. A concave mirror has an object
placed 75 cm in front of it. An image is
formed in 90 in front of the mirror.
What is the nature of the image?
Calculate the magnification of the
image and the focal length of the
mirror.
6. 5. A concave mirror has a radius of curvature of
8 m. An object is placed in front of the mirror
and an image with a magnification of 4 is
formed. What can you deduce about the nature
and location of the image? Draw a ray diagram
to show the image formed by the mirror.
Calculate the object and image distances.
