Question

True or false: Clearly write whether the statement is true or false in the blank. Write a brief explanation for the reasoning used to arrive at your answer in the space provided, 1 point each. 1) A transverse mechanical wave passes through a material. This is a transverse wave if portions of the material undergo simple harmonic motion in the direction of the wave's motion Answer 2) Two longitudinal waves with different amplitudes are observed. The wave with the greatest intensity is the one with the largest distance between its compressions. Answer_ 3) The speed of a wave is measured. Increasing its wave number while decreasing is angular frequency can leave the phase speed unchanged. Answer 4) The speed of a transverse wave along a string is measured. If the rope was more massive but also held under a greater tension then the wave's speed could remain unchanged. Answer 5) Two pulses of unequal amplitude travel toward each other along a string. The pulses exactly cancel out when passing through each other if they are completely out of phase. Answer
