Aim:

To determine the relationship between the power of the vocal lens, object and the image distance from the lens.

Apparatus:

Bulb

Projector

Convex lens

Lens holder

Screen

Optical Bench

12V power supply

Diagram:

Method:

* Set up the apparatus as shown in diagram.

* Put the focal lens at the first distance shown on the results. Also put the object at the 0 point of the optical bench.

* Switch the 12V bulb and move the projector until a clear picture of the object is visible.

* Record the results on the results table of the distance from the lens to the projector

* Keep on moving the object to the 6 points shown on the results table and record the distances when object is visible for each measurement

* I will do the experiment twice for each measurement to ensure that the results are accurate

Safety:

Making sure that all bags are put under tables will make this experiment
