Aim: To find out if the power generated by a solar panel will vary with different colours of light.
Hypothesis: All colours of light generates the same amount of energy.
Equipments:
⚨ Solar Panel
⚨ 4 wires
⚨ Multimeter
⚨ Resistor
⚨ Lamp with cardboard encircled around the light, leaving an opening
⚨ 40W, 60W and 100W light bulbs
⚨ Colour filters (red, orange, yellow, green, blue, violet)
⚨ Dark room
Method:
1. Connect one wire from the positive pole of the solar panel to the positive pole of the resistor and another wire to the positive pole of the voltmeter.
2. Connect one wire from the negative pole of the solar panel to the negative pole of the resistor, and another wire to the negative pole of the voltmeter.
3. Place the red colour filter in front of a 40W light
4. Place the solar panel underneath this now coloured light.
5. Observe the voltmeter and record the volts shown.
6. Repeat steps 4 - 5 for the other 5 colours and also perform the same steps without any colour filter.
7. Repeat steps 3-6 with a 60W light,
8. Repeat steps 3-6 with a 100W light.
Of course, this is just an early stage of the assignment, so this report might need a little revising as I move along. But here's the general idea.
BYEEE!
