Waves are vibrations that move through a medium, such as air or water. Waves can be mechanical, like sound waves, or electromagnetic, like light. Waves can be measured by their wavelength, frequency, and amplitude.
Waves: What are they?
Mechanical Wave -Longitudinal Wave -Sound Wave Transverse Wave - Water Wave
Waves That We Have Experienced.
The highest wave ever recorded was in Alaska in 1958 and measured 1,717 feet (524 meters) high. The power of a single wave can be enough to light up 10,000 homes.
Did you know?
Transverse Wave: A wave that causes the particle in the medium to vibrate in a direction perpendicular to the wave's direction of travel.
Longitudinal Wave: A wave that causes the particle in the medium to vibrate in a direction parallel to the wave's direction of travel.
The ripples on the surface of the water. The secondary waves of an earthquake. Electromagnetic waves. The waves on a string. The ocean waves.
Sound waves in air. The primary waves of an earthquake. The vibration of a spring. The fluctuations in a gas. The tsunami waves.
