When a wave traveling in a material reaches a boundary with another material in which the wave speed is faster, the reflected wave is O phase shifted by T and smaller in amplitude than the transmitted wave. O phase shifted by T and larger in amplitude than the transmitted wave. not phase shifted and has smaller amplitude than the transmitted wave. O not phase shifted and has larger amplitude than the transmitted wave.

Answer allthe given questions please

A standing wave has the following wave-function: y(x,t) = 0.2 sin(TIX) cos(12Ttt), where x and y are in meters, and t is in seconds. If the length of the string is L = 2 m and it is fixed at both ends, then the harmonic, n, in which the string is vibrating is: O n= 3 O n= 6 O n = 5 n = 2 n = 4 A standing wave with wavelength A = 1.2 m and frequency f = 50 Hz is generated on a stretched cord. For an element of the cord at x = 0.5 m, the maximum transverse velocity is v(y,max) = 2t m/s. The amplitude A of each of the individual waves producina the standing wave is:

The transverse displacement of a stretched string from equilibrium as a function of time and position is given by: Evaluate y%30.13cos(9 x + 27 t). x and y are in m; t is in s. The wave moves in the positive x direction. The speed of the wave is v The wavelength is ..... 1 m. The period is ..... 0.1 seconds. False False ..... 4 m/s. False False A traveling wave can be any function of (2*pi*x/lamda-2*pi*t/period). Calculate the various parameters where needed then select the proper answers. Submit Answer Incorrect.
