## What is the difference between the crest of a wave and the trough of a wave?

The highest surface part of a wave is called the crest, and the lowest part is the trough. The vertical distance between the crest and the trough is the wave height.

## What is the difference between a longitudinal wave and a transverse wave?

In a transverse wave, the particles are displaced perpendicular to the direction the wave travels. In a longitudinal wave the particles are displaced parallel to the direction the wave travels. An example of longitudinal waves is compressions moving along a slinky.

## What is the crest of a sound wave?

From Wikipedia, the free encyclopedia. A crest point on a wave is the maximum value of upward displacement within a cycle. A crest is a point on a surface wave where the displacement of the medium is at a maximum. A trough is the opposite of a crest, so the minimum or lowest point in a cycle.

## What is the top of a transverse wave called?

Transverse waves have what are called peaks and troughs. The peak is the crest, or top point of the wave and the trough is the valley or bottom point of the wave.

## Can transverse waves pass through liquids?

Transverse waves are waves in which the displacement of the medium is perpendicular to the direction of propagation of the wave. Transverse waves cannot travel in liquid because there is no mechanism to drive motion perpendicular to the propagation of the wave.

## What is the progressive wave?

A wave which travels continuously in a medium in the same direction without the change in its amplitude is called a travelling wave or a progressive wave.

## Is light a progressive wave?

Types of Waves They move energy in the form of vibrating particles or fields. There are two different types of progressive waves: Transverse waves – vibrations are perpendicular to the wave motion – so if the wave is travelling horizontally, the vibrations will be up and down. For example, light and water.
