1. Which one of the following indicates the wavelength of a travelling wave?
A. The distance between an adjacent trough and peak.
B. The amplitude of the wave.
C. The distance between a node and antinodes.
D. The distance between two adjacent points which are in phase.



Answer :

Final answer:

The wavelength of a wave is the distance between points in phase. Amplitude measures the maximal displacement from equilibrium. Understanding wavelength is essential for comprehending wave behavior.


Explanation:

Wavelength of a wave refers to the distance between any two adjacent points that are in phase. It can be measured from crest to crest or trough to trough, denoted by the symbol lambda ([tex]\(\lambda\)[/tex]).

The amplitude of a wave is the maximal distance a particle in the medium is displaced from its equilibrium position. It is measured from the midpoint to the peak/trough of the wave.

Understanding the concept of wavelength is crucial in grasping how waves propagate and interact in various mediums.
