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.
Sound waves with frequencies above 20000 hz?
"can't be heard by humans."
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 is the useful energy in a whistle?
acoustic energy, when you make sound it is audible because it is in sound waves that move through the atmosphere and into you ear to vibrate your eardrum
How are sound waves useful in healthcare?
they help healing
What is an ultrasonic wave?

What is the amplitude of sound waves that can be heard by humans?
LOUDNESS
What are two waves that humans are exposed to every day?
1. Light waves / Electromagnetic waves (includes gamma radiation)2. Sound waves - while sound waves are not objects, and they require a medium to travel through, we are still exposed to sound daily.
What do you understand by following terms-infrasonic waves?
Sound waves at frequencies lower than humans can hear.
Sound waves with frequencies above 20000 hz?
"can't be heard by humans."
Why can't you hear underwater?
Sound waves accessible by humans are attenuated in water.
Sound Engineers use trigonometry?
Trigonometry is used to define triangles, but it is also useful in the representation of waves. Sound engineers, obviously, use deal with sound waves. The pitch, volume, and direction of a sound wave are all deeply rooted in trigonometry.
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
Why can't you hear clearly underwater?
Sound waves accessible by humans are attenuated in water.
What is the useful energy in a whistle?
acoustic energy, when you make sound it is audible because it is in sound waves that move through the atmosphere and into you ear to vibrate your eardrum
