Question

The spacers will prevent Newton's rings and wet spots that often appear on glossy prints."

a) True
b) False

Answer 1

Spacers do not prevent Newton's rings. Newton's rings are interference fringes formed by the reflection of light between two plano-convex lenses with their plane surfaces in contact. They are used to measure flatness of optical surfaces and thin film thickness.

Step-by-step explanation:

False. Spacers do not prevent Newton's rings. Newton's rings are interference fringes created when two plano-convex lenses with their plane surfaces in contact are placed together. These rings are formed due to the interference between the light reflected off the two surfaces. Examples of applications of Newton's rings include measuring the flatness of optical surfaces and determining the thickness of thin films.
