1.
A ray parallel to the principal axis passes through a converging lens. It is refracted
straight on, unchanged
back towards the object
along the axis
through the principal focus
2.
Which ray is not deviated by a thin lens?
One through the centre
One through the focus
One at the edge
One parallel to the axis
3.
The distance from the lens centre to the principal focus is the
image distance
focal length
magnification
object distance
4.
A diverging lens always forms an image that is
virtual and inverted
real and inverted
real and upright
virtual and upright
5.
An object is 3.0 cm tall and its image is 1.5 cm tall. The magnification is
0.5
1.5
2.0
4.5
6.
For a thicker, more curved converging lens compared with a thin one
f is longer
f is shorter
f is the same
the lens becomes diverging
