The ratio $C_p /C_v$ for a diatomic gas is more than that for a monotomic gas. The molecules of a monotomic gas have more degree of freedom than those of a diatomic gas.
Newton?? 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. 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.
