b. Virtual images appear on same side of the lens as the object and have a negative value for the image distance.
c. Real images appear on the opposite side of the lens from the object and have a negative value for the image distance.
d. The focal length f is negative for converging lenses.
e. Virtual images appear on same side of the lens as the object and have a positive value for the image distance.

Answer 1

a) false

b) True

c) True

d) False

e) False

Step-by-step explanation:

a) False

For a diverging lens, the focal length is negative while it is positive for a converging lens

b) True

Image distances for virtual images are always negative and it also forms on the the same side of the lens as the object and is enlarged

c) True

d) False

For a diverging lens, the focal length is negative while it is positive for a converging lens

e) False

Image distances for virtual images are always negative and it also forms on the the same side of the lens as the object and is enlarged
