Question

why do we use a slide made of glass to place the material to be observed ​

Answer 1

Answer:

A microscope slide is a thin sheet of glass used to hold objects for examination under a microscope. ... The cover glass serves two purposes: (1) it protects the microscope's objective lens from contacting the specimen, and (2) it creates an even thickness (in wet mounts) for viewing.

Answer 2

Slides are made of glass because glasses are transparent which means that they allow light to pass through them.

• Therefore we use a slide made of glass to place the material to be observed as a transparent surface is required to pass the light of the material which is to be observed.
• A glass slide is a thin, flat and rectangular shaped piece of glass which is used as a platform to observe microscopic specimen.
