What is the height of a wave called?
As is shown on the figure, wave height is defined as the height of the wave from the wave top, called the wave crest to the bottom of the wave, called the wave trough. The wave length is defined as the horizontal distance between two successive crests or troughs.
What makes up a wave?
Waves are created by energy passing through water, causing it to move in a circular motion. The ocean is never still. Wind-driven waves, or surface waves, are created by the friction between wind and surface water. As wind blows across the surface of the ocean or a lake, the continual disturbance creates a wave crest.
What do all waves have in common?
All kinds of waves have the same fundamental properties of reflection, refraction, diffraction and interference, and all waves have a wavelength, frequency, speed and amplitude. A wave can be described by its length, height (amplitude) and frequency. All waves can be thought of as a disturbance that transfers energy.
What do waves not carry?
Classical waves transfer energy without transporting matter through the medium. Waves in a pond do not carry the water molecules from place to place; rather the wave’s energy travels through the water, leaving the water molecules in place, much like a bug bobbing on top of ripples in water.
What is it called when a wave strikes an object and bounces off?
Reflection occurs when a wave strikes an object and bounces off of it.
What occurs when a wave bounces back after striking something?
Reflection occurs when a wave bounces back after striking something.
What are waves that strike an object called?

When a wave passes through an opening?
When a wave passes the edge of an object or passes through an opening, the wave bends. That is called DIFFRACTION. A wave also bends when it passes from one medium to another at an angle. That is called REFRACTION.
What type of waves cancel out each other?
Destructive interference occurs when waves come together in such a way that they completely cancel each other out. When two waves interfere destructively, they must have the same amplitude in opposite directions.
When a wave passes through a barrier?
Reflection involves a change in direction of waves when they bounce off a barrier; refraction of waves involves a change in the direction of waves as they pass from one medium to another; and diffraction involves a change in direction of waves as they pass through an opening or around a barrier in their path.
What happens when two waves overlap?
Destructive interference occurs when the crests of one wave overlap the troughs of the other wave, causing a decrease in wave amplitude. When waves are reflected straight back from an obstacle, the reflected waves interfere with the original waves and create standing waves.
What happens to the amplitude of the resulting wave when two waves overlap?
Also called superposition. When overlapping waves produce a wave with an amplitude that is the sum of the individual waves. When overlapping waves produce a wave with an amplitude that is less than the sum of the individual waves.
When two waves interfere destructively what changes?
This is known as destructive interference. In fact, if the two waves (with the same amplitude) are shifted by exactly half a wavelength when they merge together, then the crest of one wave will match up perfectly with the trough of the other wave, and they will cancel each other out.
Do all waves carry energy?
Do all waves carry energy? Light, heat, radio, and similar types of energy are carried by a variety of waves in the ELECTROMAGNETIC SPECTRUM. Some energy waves need a medium, such as water or air, through which to travel.
