Two strings under the same tension `T` but with different values of the mass per unit length `mu_(1)` .and `mu_(2)` are connected together. A traveling wave pulse of amplitude `1 cm` is incident on the boundary,going from `mu_(1)` to `mu_(2)` .If `mu_(2)=0.1 mu_(1)` ,what is approximately the amplitude of the transmitted pulse?

Two thin rods of same length l but of different uniform mass per unit length mu_(1) and mu_(2) respectively are joined together. The system is ortated on smooth horizontal plane as shown in figure. The tension at the joint will be

If mu_(1) and mu_(2) are aboslute refractive index of medium 1 and medium 2 respectively, then

Two strings with linear mass densities mu_(1)=0.1kg//m and mu_(2)=0.3kg//m are joined seamlesly. They are under tension of 20N . A travelling wave of triangular shape is moving from lighter to heavier string.

An e.m. wave is travelling through a medium of refractive index mu_1 , and is incident on the boundary of a medium of refractive index mu_2 . IF the wave reflects at the boundary

Two strings A and B are connected together end to end as shown in the figure. The ratio of mass per unit length (mu_(B))/(mu_(A))=4 . The tension in the string is same. A travelling wave is coming from the string A towards string B. if the fraction of the power of the incident wave that goes in sting B is (n)/(9) the value of n is:

If a ray of light takes t_(1) and t_(2) times in two media of absolute refractive indices mu_(1) and mu_(2) respectively to travel same distance, then

A string consists of two parts attached at x=0 , The right part of the string (xlt 0) has mass per unit length mu_r and the left part of the string (xlt 0) has mass per unit length mu _l The tension in the string is T. If a wave of units amplitude travels along the left part of the string,what is the amplitude of the wave that is transmitted to the right part of the string?

If refractive index of core & cladding are mu_(1) & mu_(2) respectively then :

The dimensions of [mu_(0)in_(0)]^(1/2) are :
