JEE Main 2015 Discussion Forum › Optics questions › OPTICS 3

A THIN COAT OF TRANSPARENT SUBSTANCE WITH A REFRACTION INDEX `n` LOWER THAB THAT OF THE GLASS IS APPLIED TO THE SURFACE OF OPTICAL GLASS[COATED GLASS] TO REDUCE ITS REFLECTION FACTOR[REFLECTANCE].ESTIMATE THE THICKNESS OF THE COAT IF THIS LIGHT RAYS ARE INCIDENT ALMOST NORMALLY ONTO THE OPTICAL GLASS.

relfectance will be given by R = r / ( i + r) R is reflectance and others have usual meanigs.

can we use this idea here?
