Which one of the following types of glasses can scatter ultraviolet rays?

Jena glass is capable of scattering ultraviolet (UV) rays due to additives like cerium oxide incorporated into its composition. The correct answer is [C] Jena glass. These additives absorb and scatter UV radiation effectively, making Jena glass suitable for applications requiring UV protection. This includes optical lenses, scientific instruments, and protective eyewear where shielding against harmful UV rays is essential. Option A, soda glass, does not possess inherent UV scattering properties and is used in everyday glassware. Option B, Pyrex glass, is known for its resistance to thermal shock and is not specifically designed for UV protection. Option D, Crookes glass, is used in scientific instruments and cathode ray tubes but does not inherently scatter UV rays. Therefore, Jena glass (option C) stands out as the type of glass capable of effectively scattering ultraviolet rays due to its composition and additives designed for UV protection and absorption.
