Experiment 7 Refractive index for transition from air to acrylic glass

Topics covered in the experiment

• The direction of a ray of light changes when it passes from air to transparent medium.

• A ray of light that is incident at an angle on a transparent body emerges from this body at a definite angle.

• If the angle of refraction is known, the refractive index can be calculated.

• The refractive index depends on the material.

Parts required

from the Student Kit – Optics (U60050)

1 optic bench

1 optical light

1 experiment table

1 single aperture slot

1 semicircular body

1 diaphragm holder

1 lens, f = +100 mm

1 overlay mask "protractor"

Setup

f = +100 mm

Figure 1

1) Position the optical light with its exit opening on the 25 cm mark and the lens (f = +100 mm) at the 34 cm

mark on the optic bench.

2) Position the experiment table directly behind the optic bench.

3) Connect the optical light to the plug-in power supply unit.

4) Move the lens in such a way that the light spreads out in a parallel beam over the surface of the table.

5) Place the overlay mask "protractor" on the experiment table.

6) Position the diaphragm holder on the optic bench to the immediate right of the lens.

7) To create a single ray of light place the single aperture slot in the diaphragm holder and make sure that the

ray of light falls as accurately as possible on the 0° line.

8) Place the semicircular body on the overlay screen in such a way that its longitudinal side lies exactly on the

90° line and is divided into two parts by the 0° line (please see Figure 1).
