What is an ultrasonic wave?
Ultrasonic waves are sound waves with frequencies higher than what humans can hear. Sound waves have frequencies of about 20,000 to 100,000.
How are sound waves useful to humans?
It helps you by, if the phone rings you hear it. you can listen for danger
Do sound waves exist even if you can't hear them?
Yes, sound waves exist which are not audible to the human ear. Humans can hear sound waves having frequency between 20 - 20,000 Hz. Other all frequencies lie outside our hearing range and are called ultrasonic or supersonic waves.
Where are sound wave collected to allow humans to hear?
Sound waves are collected at the outer ear.... it funnels the sounds into the ear canal
What do you hear when 2 sounds waves cancel each other out?
When two waves interact via deconstructive interference, then you would hear nothing if you stood in that exact spot. If two waves interact via constructive interference, then you would hear a sound that is the sum of both waves.
Can animals hear primary waves?
it is proven that most animals can hear waves through earthquakes. but humans can just feel the "bump".
Can humans hear infrasonic waves?
With special technology, yes
Can humans hear radio waves?
As defined by research on the topic of the Electromagnetic Spectrum, no human can hear radio waves. No human can hear any part of the Electromagnetic Spectrum except gamma rays, which have enough energy to light up. If humans were to hear radio waves, they wouldn't need radios (except from the original form).
What do you understand by following terms-infrasonic waves?
Sound waves at frequencies lower than humans can hear.
Why can't you hear underwater?
Sound waves accessible by humans are attenuated in water.
What is an ultrasonic wave?
Ultrasonic waves are sound waves with frequencies higher than what humans can hear. Sound waves have frequencies of about 20,000 to 100,000.
How are sound waves useful to humans?
It helps you by, if the phone rings you hear it. you can listen for danger
What are ultrasonic and infrasonic waves?
Infrasonic waves are waves which are below humans hearing range while ultrasonic waves are waves which human beings can hear. Example-bat,dog etc and human beings (respectively)
Why can bat hear much higher sounds than humans?
bats can hear sounds of higher frequency than humans (supersonic) because they produce them and these sound waves echo back to them by bouncing of items so that they can see how far something is. Just like in submarines. therfore they need to 'hear' these 'supersonic' waves to see.
Do sound waves stop when losing hearing?
in a way, but there are still some there, humans just cant hear them.
Do sound waves exist even if you can't hear them?
Yes, sound waves exist which are not audible to the human ear. Humans can hear sound waves having frequency between 20 - 20,000 Hz. Other all frequencies lie outside our hearing range and are called ultrasonic or supersonic waves.
Infrasonic wave and ultrasonic wave?
