Waves are formed by any disturbance upon a fluid medium. 2. Surface ocean waves are formed by wind stress. If the wind is weak, capillary waves form. Their restoring force is capillarity (caused by the hydrogen bonds between water molecules). If the wind is stronger, gravity waves form. Their restoring force is gravity. 3. Tsunamis are formed as a result of undersea disturbances. These can be tectonic movements, like earthquakes, but they can also be caused by landslides, as in the one that occurred in Anchorage, Alaska. Tsunamis are barely noticable in the open ocean, but their wave steepness and wave speed increase tremendously as they approach shore.
A mechanical wave travels through a medium because a medium is necessary for the propagation of that wave. With a mechanical wave, like sound, mechanical energy is put intothe wave, and the medium carries the energy of the wave. This is in contrast to an electromagnetic wave (like light) which can move through a total vacuum.
L-wave
Air near the ground is not directly heated by sunlight. Sunlight heats the surface of the Earth with (mostly) short-wave energy. The surface of the Earth absorbs this short-wave energy and emits long-wave energy. This long-wave energy is what heats air near the ground. When air is heated, it expands, becomes lighter, and rises higher in the atmosphere. This is the driving force behind all weather on the planet.

Energy moves forward in a wave.
The energy of a wave moves forward with the wave. A wave is moving energy, and the wave carries it in the direction of propagation.
It is a wave like because the curve it makes is the amplitude as that of wave
The heat wave in the story "Heat Wave" acts as both a setting and a catalyst for the events that unfold. It creates a tense and oppressive atmosphere, mirroring the characters' internal struggles and emotions. The heat wave is an external force that influences the characters' actions and decisions, driving the plot forward.
the upper part of the wave moves faster
In a transverse wave, a molecule/particle will move up and down, with double the amplitude of the wave. In a longitudinal wave, the molecule/particle will move side to side, equal to the wavelength (?) of the wave
A snake's body make a transverse wave as the snake moves forward.
Perpendicular. Light wave moves forward, the crests move at right angles to the wave
eureka rush for new wealth wave of migration for gold but none of them is as good as old 'gold rush'
Transverse wave
Transverse wave
The wave is not strong enough to move the object forward. It just passes along under the object and goes on its way.
