Question

A wave along a string has the following equation where x is in meters and t is in seconds. Y = 0.02 sin(24 t – 4.3 x) mm. Find the amplitude of the wave?

Answer 1

Answer: 0.02 mm

Explanation: General equation for wave has amplitude as the number that is multiplied by the trig ratio sine or cosine. The number in this case is 0.02. Since the y-value is in mm, the amplitude is 0.02 mm.
