What are the classifications of waves?
Categorizing waves on this basis leads to three notable categories: transverse waves, longitudinal waves, and surface waves. A transverse wave is a wave in which particles of the medium move in a direction perpendicular to the direction that the wave moves.
Is am the same as LW?
The term AM is commonly used to cover both Medium Wave (MW) and Long Wave (LW).
Is Long wave still used?
Many Middle East and North African countries use the band, or have unexploited allocations. It’s often said to be an obsolete band, but this is not true as. Not only do millions listen to Long Wave stations every day, but there are plans to increase the number of Long Wave Radio stations.
How are waves able to travel across the ocean?
However, water does not actually travel in waves. Waves transmit energy, not water, across the ocean and if not obstructed by anything, they have the potential to travel across an entire ocean basin.
How are water waves different from transverse waves?
Water waves are surface waves, a mixture of longitudinal and transverse waves. Surface waves in oceanography are deformations of the sea surface. The deformations propagate with the wave speed, while the water molecules remain at the same positions on average. Energy, however, moves towards the shore.
What kind of motion does a water wave have?
Each particle in the medium experiences simple harmonic motion in periodic waves by moving back and forth periodically through the same positions. Consider the simplified water wave in Figure 13.2. This wave is an up-and-down disturbance of the water surface, characterized by a sine wave pattern.
Why do waves travel in a circular motion?
Waves are created by energy passing through water, causing it to move in a circular motion. However, water does not actually travel in waves. Waves transmit energy, not water, across the ocean and if not obstructed by anything, they have the potential to travel across an entire ocean basin.
