Hello Aspirant,

Hope you are doing great. Stone is opaque because light cannot pass through it, whereas glass is transparent because it allows light to pass through it. An object is transparent if you can see clearly through it and it allows light to pass through. for instance, clear glass, water, etc. Opaque Objects the an object is opaque if we cannot see through it at all. For instance, a wall or door made of wood.

ALL THE BEST

hiiii

1st of all your question is wrong.

the stonea are not transparent where as glass are transparent.

the transparency of a substance depends on the material of which the substance is made  if beems of light reflected back after fall from the substance surface then the substance is called opaque or if the beem of light easily passes through the material then the substance is called transparent.

hope this will help you to understand

best of luck for your future
