Question

A bunch of PY112 students line up at the front of the class and make a people wave by putting their arms over each other's shoulders and having the person at the end of the line bend forwards. (b) (i) What type of wave is travelling along the Jine of students? (ii) If the person bends forward more, wilthe wave travel faster down the line? Explain your aswer. becaute the coave enegy wilt be ismass(the Derson bend ram ies+ to ria (ii) Will the wave energy propagate faster.or slower, if instead Sooard of PY112 students, there is a line of NFL players? ock Explain your reasoning. while

Explanation / Answer

1) transverse wave : since the direction of the particles undergoing displacement and the direction of energy transfer are perpendicular to each other.

3) The wave speed depends on the medium in which the wave propagates and on the particles undergoing oscillation. Now since people have been replaced by NFL players, the speed will be faster as compared to the wave with students involved.
