Question

1. define a \wave\. also discuss what \wavelength\ and \frequency\ mean.

Explanation:

A wave is a disturbance that transfers energy through a medium (or in some cases, through a vacuum like electromagnetic waves). Wavelength is the distance between two consecutive points in a wave that are in - phase (e.g., two crests or two troughs). Frequency is the number of complete wave cycles that pass a given point per unit time.

Answer:

A wave is a disturbance that transfers energy. Wavelength is the distance between two consecutive in - phase points on a wave. Frequency is the number of wave cycles per unit time.
