Which one of the following types of glass can cut off ultraviolet rays? A. Soda glass B. Pyrex glass C. Jena glass D. Crooked glass

Soda glass
Pyrex glass
Jena glass
Crooked glass

The correct answer is: A. Soda glass.

Soda glass is a type of glass that is made from silica, soda ash, and lime. It is the most common type of glass used in windows, bottles, and other containers. Soda glass has a low melting point, which makes it easy to work with. It is also relatively inexpensive to produce.

Soda glass can block ultraviolet rays because it contains iron oxide. Iron oxide absorbs ultraviolet light, which prevents it from passing through the glass. This makes soda glass a good choice for applications where it is important to protect people from exposure to ultraviolet light, such as in windows and sunglasses.

Pyrex glass is a type of borosilicate glass that is made from silica, boric oxide, and soda ash. It is a more heat-resistant type of glass than soda glass. Pyrex glass is often used in cookware and laboratory equipment.

Jena glass is a type of optical glass that is made from silica, soda ash, and lime. It is a high-quality type of glass that is used in lenses, prisms, and other optical instruments.

Crooked glass is a type of glass that is not flat. It is often used in decorative applications, such as stained glass windows.

In conclusion, the correct answer is: A. Soda glass.
