After SHM SHM here is waves tread..i dont have a lot of questions on this topic..but i will psot some good ones for all....
Here are first 5 questions..i will post more if they are solved..
Q1
Q2
Q3 How long will it take for the sound waves to travel distance l between poits A and B if the air temperature between them varies linearly from T1 to T2.The velocity of sound in air is v=α√T
Q4 a unifrom string is clamped at x=0 and x=L and is vibrating in fundamental mode.mass per unit length=μ,tension=T and max displacement form mid point =A.Find total energy stored in string.Assume A to be small
Q5 If temp of stretched wire dec. by 1%,denity inc by %,Young modulus dec by 0.5 %,coeff of linear expansion inc by 1.5%.So find % change in velcity of transvere wave in wire
