What do we need?
1
Optical lamp
with power supply unit
1
Base plate
1
Screen
1
Focusing lens (flat design)
1
Mask
additionally required:
1
Ruler
Conducting the experiment
1.
Attach the mask to the screen!
2.
Place the optical lamp on the left side of the base plate, so that the light emerges parallel to the
right!
3.
Place the screen in front of the optical lamp!
4.
Place the focusing lens as marked on the mask!
5.
Observe the wide beam of light before passing through the lens and afterwards!
6.
Draw it onto the mask! Transfer it into the sketch!
7.
Describe the way the beam of light reacts when passing through a focusing lens!
