Will not be refracted because of the angle of incidence.
Will not be refracted because of the critical angle.
Will be refracted towards the normal.
Will be refracted away from the normal.

 

The ray does not reflect.
The ray reflects back upon itself.
The reflected ray travels along the surface of the glass.
The ray passes through the glass to form a virtual image.

 

At the focal point if the incident rays are parallel.
At the focal point if the incident rays diverge from the source.
At the focal point if the incident rays converge from the source.
In front of the focal point if the incident rays diverge from the source.

 

Converge at the focal point.
Converge behind the focal point.
Converge in front of the focal point.
It depends on whether the rays from the point source converge or diverge.

 

When the object is outside the focal length.
When the object is inside the focal length.
When the object is either inside or outside the focal length.
Regardless of the object position.
