When monochromatic light is incident on a surface separating two media, the reflected and refracted light both have the same frequency as the incident frequency. Explain, why.

Two wires of equal length, one of aluminium and the other of copper have the same resistance. Which of the two wires is lighter? Hence explain why aluminium wires are preferred for overhead power cables. ( rho_Al = 2.63 xx 10^-8 Omega m, rho_Cu = 1.72 xx 10^-8 Omega m . Relative density of A1 = 2.7, of Cu = 8.9.)

Out of a swarm of bees,one fifth settled on a blossom of Kadamba ,one third on a flower of Silindhiri and three times the difference between these two numbers flew to the blosssonKutaja.Only ten bees were the left from the swam.Whatwas the number of bees in the swarm?(Note,Kadamba,Silindyhiri anbd Kutaja are flowering trees.The problem is fom the ancient Indian text on algebra.)

Is it possible to have interference between the waves produced by two violins? Why?

Two sitarstrings A and B playing the note ‘Ga’ are slightly out of tune and produce beats of frequency 6 Hz. The tension in the string A is slightly reduced and the beat frequency isfound to reduce to 3 Hz. If the original frequency of A is 324 Hz, what is the frequency of B?

A man running a race-course notes that the sum of the distances from two flag posts from him is always 10 m and the distance between the flag posts is 8 m. Find the equation of the path traced by the man.
