Question

3 multiple choice 1 point if two rope waves are made using the same rope but one has more crests passing per second, what can you infer about that wave compared to it has a higher frequency and shorter wavelength it has a lower frequency and longer wavelength it has the same frequency and amplitude it has a lower frequency and shorter wavelength 4 multiple choice 1 point which statement correctly compares the movement of the medium in a transverse wave and a longitudinal wave? transverse waves move perpendicular, longitudinal waves move parallel transverse waves move parallel, longitudinal waves move perpendicular both move perpendicular to the direction the wave travels

Explanation:

• Question 3: Frequency is the number of crests (or troughs) passing a point per second. So more crests per second means higher frequency. For waves on a rope (assuming same wave speed \(v\), since same rope), using the wave equation \(v = f\lambda\) (where \(v\) is wave speed, \(f\) is frequency, \(\lambda\) is wavelength). If \(v\) is constant (same rope, same tension etc.), \(f\uparrow\) implies \(\lambda\downarrow\).
• Question 4: In a transverse wave, the medium moves perpendicular to the direction of wave propagation. In a longitudinal wave, the medium moves parallel to the direction of wave propagation.

Answer:

• Question 3: It has a higher frequency and shorter wavelength
• Question 4: Transverse waves move perpendicular, longitudinal waves move parallel
