The type of glass used in making lenses and prism is

A. Pyrex glass
B. Jena glass
C. Flintglass
D. Soft glass

Check Answer

The correct answer is C) Flintglass.

Flint glass is a type of optical glass that is used for making lenses and prisms due to its high refractive index and low dispersion. It is made by adding lead oxide to silica during the manufacturing process, which increases the density and refractive index of the glass. This makes it an ideal material for creating lenses and prisms with high magnification and clarity.
