What is the relationship between mechanical waves and vibrations?
A mechanical wave requires a material medium in order to travel, vibrations are able to move through the air unaided. While they have different traveling mechanisms, a vibration can be considered as a type of mechanical wave.
Do light waves need to move through a medium?
No
What is required for a mechanical wave to move?
a source of energy for it to originate from, and a medium in which to move through
What do you call the maximum distance that the particles of a medium move from the rest position?
The amplitude.
Why do sound needs a material medium for their propagation?
We know that sound is a mechanical wave and as such, it transfers energy into the medium through which it travels as a means to propagate itself. Without a medium through which to progagate, a mechanical wave cannot move.
Why does sound not travel through space?
Sound does move through space. It doesn't move though empty space, i.e. a vaccuum. In outer space there is a vaccuum (though not necessarily a perfect vaccuum).Sound is caused by vibrations in a medium such as air (or water or wood). These vibrations compress and rarefy the medium. The vibrations move through the medium as waves.In a vaccuum, there is no medium thus there is no sound.
How does sound move through a medium?
Vibrations are carried through the atoms in a structure. When these vibrations travel through air, they are amplified by the ear drum and sensed by nerves as sound.
What is the relationship between mechanical waves and vibrations?
A mechanical wave requires a material medium in order to travel, vibrations are able to move through the air unaided. While they have different traveling mechanisms, a vibration can be considered as a type of mechanical wave.
A sound wave travels equal distances through air water and aluminum. Which medium will it move through in the shortest time?
Aluminum
How do vibrations move through earth's crust?
There are three types of vibrations:- Primary waves, Secondary waves and long waves. Primary waves can move through solid and liquid. Secondary waves move through only solids and long waves can only move along the surface of the earth's crust.
What is the best statement to describe vibrations that move through earht quakes?
through a series of elevated pulses
Do light waves need to move through a medium?
No
How are vibrations and fluid currents transmitted?
Sound consists of vibrations in the medium through which the sound is traveling. When the sound-producing object vibrates, it sets the neighbouring particles of the medium into vibration. These in turn pass the vibration to their neighbouring particles. After doing this, they come back to rest. This way the disturbance is carried forward and when these vibrations are sensed by our ear, we hear sound.
What is the maximum distance the particles of the medium move away from the rest positions as a wave passes through the medium?
The maximum distance the particles move away from their rest positions as a wave passes through a medium is the amplitude of the wave.
What is required for a mechanical wave to move?
a source of energy for it to originate from, and a medium in which to move through
What is required to create sound?
vibration and a medium for it to move through
What starts avalanches?
When a sound is too high it echos and makes the snow move by vibrations causing what we call avalanches
