Glass Slab

Product Code : SCL-LAO-14580

Indian Lab Suppliers supplies the Glass Slab (Product ID: 14580) as part of its light and optics range. It is a rectangular glass slab with parallel polished faces for refraction and lateral displacement experiments.

Quick Answer

A ray passing through the slab bends towards the normal on entry and away from it on exit, so it leaves parallel to the incident ray but shifted sideways. Students trace the path with pins on paper, measure the angles i and r, and calculate n = sin i / sin r, which should come out near 1.5. Sizes are 75 × 50, 100 × 50 and 100 × 60 mm, 10–15 mm thick, with bevelled or rounded edges for safer handling.

Frequently Asked Questions

Why does the ray come out parallel?
The two faces are parallel, so the bending at entry and exit cancels.

What refractive index should students get?
About 1.5.

Which sizes are available?
75 × 50, 100 × 50 and 100 × 60 mm.
