What do we need?
1 Optical lamp
with power supply unit
1 Base plate
1 Screen
1 Plexiglass pane
1 Mask
additionally required:

st
experiment
1. Attach the mask to the base plate!
2. Place the optical lamp on the left side of the base plate, so that the light emerges conically to the
right!
3. Place the screen onto the base plate as marked on the mask!
4. Put the transparent plate in front of the light source and examine how much light is transmitted!
5. Use further materials and examine how they transmit light!
6. Arrange the materials and record them in table 1 according to how they react!
