When several transparent materials are kept above each other, the resultant behaves like an opaque object.Why?What’s the Optics behind it?

When light falls on a object, three things happen –

  • A part of the light is absorbed
  • Another part is reflected ad
  • The remaining part is transmitted.

A transparent medium transmits most of the light incident on it. However, it absorbs a small part as well as reflect a small part.

Therefore, when a number of transparent sheets are stacked, the amount of light absorbed will be considerably large and the arrangement tends to be opaque.
