Question

discussion and analysis questions: 1. why was trial 1 a demonstration of only half of a wavelength? why is trial 2 a demonstration of a complete wavelength?

Explanation:

In physics, a half - wavelength is half the distance between two consecutive points in phase on a wave, and a complete wavelength is the full distance between such points. Trial 1 likely showed a displacement or pattern equivalent to half this distance, while trial 2 showed the full distance.

Answer:

The reason for trial 1 demonstrating half a wavelength and trial 2 a complete wavelength likely depends on the physical setup, displacement patterns, or wave - related measurements in the trials. Without more details about the trials, this is a general physical principle - based explanation.
