# physics: true or false

posted by .

A concave mirror of focal length 10 cm forms an upright and diminished image of a real object placed at a distance of 5 cm from the mirror.
A. True
B. False

A convex lens is used to obtain an enlarged virtual image.
A. True
B. False

Not too sure on the first one... the second one is true?

• physics: true or false -

you got the second one right.

• physics: true or false -

draw the ray diagram on the first.I get an upright virtual image behind the mirror.

• physics: true or false -

yeah, so it is false
