Reduces the time interval needed for the pulse to reach wall

Reference no: EM13676038

Assume you create a pulse by moving the free end of a taut string up and down once with your hand beginning at t = 0. The string is attached at its other end to a distant wall. The pulse reaches the wall at time t. Which of the following actions, taken by itself, reduces the time interval needed for the pulse to reach the wall? More than one choice may be correct.

Moving your hand more quickly, however still only up and down once by the same amount.

Moving your hand more slowly, however still only up and down once by the same amount.

Moving your hand a greater distance up and down in the same amount of time.

Moving your hand a lesser distance up and down in the same amount of time.

Using a heavier string of the same length and under the same tension.

Using a light string of the same length and under the same tension.

Using a string of the same linear mass density however under decreased tension.

Using a string of the same linear mass density however under increased tension.
