Physics Review Question Unit: Waves Year: 1995 Question#: 37 Question: What is the angle between the direction of propagation of a transverse wave and the direction in which the amplitude of the wave is measured? (1 ) 0 degrees (2 ) 45 degrees (3 ) 90 degrees (4 ) 180 degrees What is this question really asking? Explanation by: Maria K [ Return to question menu ] Answer 1 0 degrees INCORRECT not perpendicular return to top Answer 2 45 degrees INCORRECT not perpidicular return to top Answer 3 90 degrees CORRECT This is the only angle that is perpendicular to the propagation. Amplitude is perpendicular to the direction of the propagation, that's the definition of a transverse wave. return to top Answer 4 180 degrees INCORRECT not perpidicular return to top What's this question really asking? What's the difference in degrees between the motion of the wave and the motion of the particle? return to top |
