Which of the following types of glass can cut off ultraviolet rays ?
Explanation
Crookes glass is a specialized type of glass that contains cerium oxide (CeO2). This specific chemical addition gives the glass the unique property of absorbing or "cutting off" harmful ultraviolet (UV) rays while remaining transparent to visible light. Because of this protective quality, it is primarily used in the manufacturing of high-quality sunglasses and optical lenses to protect the human eye from solar radiation.
- Soda glass (soft glass) is the most common type used for window panes and bottles.
- Pyrex glass (borosilicate glass) is known for its high thermal resistance, making it ideal for laboratory equipment and cookware.
- Jena glass is a high-quality borosilicate glass used for scientific apparatus due to its chemical and heat resistance.
