- A trough is the lowest point of a wave, representing a position where the wave's displacement is at its minimum. This key feature is essential for understanding wave behavior, as it contrasts with the crest, which is the highest point.
As you can see, the wave is made up of consecutive peaks and troughs, which repeat continuously. You need to be aware of the following key terms: The speed (v) of a wave is equal to the wave’s frequency multiplied by its wavelength. v = f λ. The above equation can be derived using the definitions of speed, frequency and wavelength as shown below:

Longitudinal waves - oscillation of particles is parallel to the direction of energy transfer. These are made up of compressions and rarefactions and can’t travel in a vacuum. Sound is an example of a longitudinal wave, and they can be demonstrated by pushing a slinky horizontally.

Definition. A trough is the lowest point of a wave, representing a position where the wave's displacement is at its minimum. This key feature is essential for understanding wave behavior, as it contrasts with the crest, which is the highest point.
The smoother the surface, the stronger the reflected wave is. Rough surfaces scatter the light in all directions, so appear matt and not reflective. The angle of incidence = angle of reflection. Light will reflect if the object is opaque and is not absorbed by the material.

A trough is a local minimum or low point in a wave pattern, occurring between two crests or peaks. It is a fundamental concept in the study of wave phenomena and is particularly relevant in the context of Young's Double Slit Experiment.
Transverse waves. Eg/ Light, or any electromagnetic wave. Have peaks and troughs. Vibrations are at right angles to the direction of travel. Longitudinal waves. Eg/ Sound waves. Have compressions and rarefactions. Vibrations are in the same direction as the direction of travel.
