Only sound energy travels in wavesTrue or false?
false because it can also travel out of waves
Is it true or false a mechanical wave transmits energy through a vacuum?
not
Is this true or false mecanical waves din't need matter to travel through?
False, mechanical waves need a medium to travel through. Electromagnetic waves, such as visible light, don't.
In a vacuum space the red laser beam travels faster then the beam of microwaves true or false?
Both beams travel at the same speed.
Is mechanical waves can travel though empty space true or false?
No, mechanical or pressure waves can not travel through empty space
Can sound waves travel in a vacuum.?
Sound cannot travel through a vacumNo. Sound waves can not travel in a vacuum. Sound works by having molecules of air knock against other molecules of air. Then those molecules knock against other molecules. The energy is transferred from one molecule to the next. These molecules we hear transferring energy from one to another we hear as sound. Where molecules can not transfer energy to another molecule, such as in a vacuum, sound can not exist.
True or false vibrations can travel through air and water?
Yes. Vibrations can travel through anything except space where there is a vacuum.
Is it true or false that all forms of energy can travel in a vacuum?
false
Sound energy cannot pass through empty space true or false?
True, sound waves can travel in all three mediums , solids liquids and gases We hear sounds in gas medium. Sonar is an application for sound in liquid. Sound can make solids vibrate upon moving.
Only sound energy travels in wavesTrue or false?
false because it can also travel out of waves
Is it true or false a mechanical wave transmits energy through a vacuum?
not
Do all waves need a medium to travel through true or false?
false
Is this true or false mecanical waves din't need matter to travel through?
False, mechanical waves need a medium to travel through. Electromagnetic waves, such as visible light, don't.
In a vacuum space the red laser beam travels faster then the beam of microwaves true or false?
Both beams travel at the same speed.
When you shout in a big room you hear your voice coming back because the sound of your voice is very loud true or false?
the sound travel fast....
Are water waves mechanical waves?
No, Mechanical waves means that the waves require a medium in order to pass through. For instance, sound is a mechanical wave because it requires the air to travel through (or any material -- such as water). Light waves are electromagnetic waves because they produce an oscillating electric/magnetic field as it travels. Also because it requires no medium to travel through, this is why the sun's light may reach us here on earth. (Note: it was previously thought that the medium in space which allowed light to travel through, this was referred to as the ether - this is false, space is a vacuum.)
