QUESTION 1 Which of the following are true of standing waves on a string? (Mark all that are true.) No points on the string over move. O They can be represented as a sum of two waves traveling in opposite directions. There are some points on the string that do not move. When a point on the string is at its maximum displacement, It is also at its maximum speed. QUESTION 2 A wave on a string with amplitude A carries power P. In order to double the power carried by the wave by changing the tension in the string while keeping the frequency and amplitude of the wave the same, I should: O increase the tension by a factor of 2 decrease the tension by a factor of V 2. increase the tension by a factor of 2. increase the tension by a factor of 4
