Assertion : Newton's rings are formed in the reflected system. When the space between the lens and the glass plate is filled with a liquid of refractive index greater than that of glass, the central spot of the pattern is bright.
Reason : This is because the reflections in these cases will be from a denser to a rarer medium and the two interfering rays are reflected under similar conditions.

In these question, a statement of asertion followed by a statement of reason is given .Choose the correct answer out of the following choices: Assertion and reason both are correct statements and reason is correct explanation for assertion. Assertion and reason both are correct statements but reason is not correct explanation for assertion. Assertion is correct statement but reason is wrong statement. Assertion is wrong statement but reason is correct statement.

Explain reflection of longitudinal wave travelling from denser to rarer medium.

Explain the reflection of transverse and longitudinal waves from a denser and a rarer medium.

Explain the reflection of transverse and longitudinal waves from a denser medium and rarer medium.

Diameter of a particular dark ring in Newton rings experiment in reflected system is 0.8 mm. When a transparent liquid of refractive index 1.6 is placed between lens and the plate, diameter of ring is approx

Explain reflection of longitudinal wave travelling from rarer to denser medium.
