Question

string telephone waves complete the following sentence stems to explain which type of wave a string telephone uses to transfer energy. a string telephone uses transverse waves because it goes up and down. it does not use longitudinal waves because

Explanation:

Step1: Understand wave - types

Transverse waves have particles vibrating perpendicular to the direction of wave propagation. Longitudinal waves have particles vibrating parallel to the direction of wave propagation.

Step2: Analyze string - telephone waves

When you speak into one end of a string - telephone, the string vibrates up and down (perpendicular to the length of the string), which is characteristic of transverse waves. It doesn't have particles vibrating parallel to the length of the string like in longitudinal waves.

Answer:

A string telephone uses transverse waves because the particles of the string vibrate perpendicular to the direction the wave travels along the string. It does not use longitudinal waves because the particles of the string do not vibrate parallel to the direction the wave travels along the string.
