Reflection And Refaction Of Waves

An incident wave is represented by y(x,t)=20sin(2x-4t) . Write the expression for reflected wave (i) from a rigid boundary (ii) from an open boundary.

Assertion :on reflection from a rigid boundary (denser medium) there is a complete reversal of phase. Reason : This is because o reflection at a denser medium. Both the particle velocity and wave velocity are reversed in sign.

The harmonic wave y_i = (2.0 xx 10^(-3)) cos pi (2.0x - 50t) travels along a string towards a boundary at x=0 with a second string. The wave speed on the second string is 50 m//s . Write expressions for reflected and transmitted waves. Assume SI units.
