How and where are the Newton’s rings formed? Give the underlying principle/mechanism.
Answers
Answer:
Newton's rings is a phenomenon in which an interference pattern is created by the reflection of light between two surfaces: a spherical surface and an adjacent touching flat surface. It is named after Isaac Newton, who investigated the effect in his 1704 treatise Opticks
Explanation:
Newton's rings are formed due to interference between the light waves reflected from the top and bottom surfaces of the air film formed between the lens and glass sheet. light. An air film of varying thickness is formed between the lens and the glass sheet.Newton's rings in transmission
So the transmitted rays near the point of contact have constructive interference in transmission. So, in a Newton's rings pattern in transmission are like negative images of those seen in reflection: a bright patch at the centre followed by a dark ring, then a bright, etc.
