Experiment: Investigate absorption of UV radiation by glass of varying thickness

1. Place a piece of glass between a UV lamp and a piece of film.
2. Measure the thickness of the glass using a micrometer screw gauge.
3. Develop the film and place it between an incandescent source and a lightmeter.
4. Note the reading from the lightmeter
5. Repeat this experiment for different thicknesses of glass
6. Draw a well-labelled diagram of the way the experiment is set-up

(a) Keep the exposure time the same for different thicknesses of glass
(b) Keep the distance between the light source and the film constant
(c) Keep the intensity of the UV source constant
(d) UV light is dangerous to the eyes so safety goggles must be worn
(e) Perform the experiment from potential natural/man-made sources of UV
(f) Carry the experiment in a dark room
