The delay caused by the loss in velocity of the electromagnetic energy propagated by the EDMI in the glass of the reflector is termed_________________

Solution

Zero Error

It happens so, because the refraction index of the prism glass is different than that of air, and therefore the velocity travels slower in glass than that in the air. Prism Index is the term used to represent the difference in the refraction index.
