Product Code : SCL-LAO-14579
Indian Lab Suppliers supplies the Semi Circular Glass Slab (Product ID: 14579) as part of its light and optics range. It is a semicircular glass block for refraction, critical angle and total internal reflection experiments.
Quick Answer
A ray aimed through the curved side at the centre of the flat face travels along a radius, so it meets the curved surface at 90° and does not bend there; all the refraction happens at the flat face. Increasing the angle inside the glass shows the refracted ray grazing the surface at the critical angle (about 42° for n ≈ 1.5), followed by total internal reflection. Diameters are 75, 100 and 150 mm, 10–15 mm thick, with flat and curved faces polished and edges smoothed. Handle with care; dropped glass can chip or break.

Frequently Asked Questions
Why is the block semicircular?
Rays aimed at the centre cross the curved face without bending, so refraction occurs only at the flat face.
What critical angle does it give?
About 42° for glass of n ≈ 1.5.
Which sizes are offered?
75, 100 and 150 mm diameter.
