What are the different types of waves that are given off by the human body?
The human body gives off different types of waves, including electromagnetic waves such as infrared radiation and radio waves, as well as acoustic waves like sound waves.
Why are sound waves different than most?
why sound waves are different than most
Can you see ultrasonic sound waves?
Sound waves- ultrasonic, sonic, or intrasonic are generally invisible. You cannot see sound.
How do aquatic animals interact with other animals?
by sound waves they send out
Why can't you hear clearly underwater?
Sound waves accessible by humans are attenuated in water.
What are infrasonic and ultrasonic sound waves?
Ultrasonic and Infrasonic sound waves are waves that are not audible to human beings. The audible region contains sound waves of 16 Hz to 20,000 Hz.Infrasonic sound waves have frequencies below 16 Hz. For example, an earthquake.Ultrasonic sound waves have frequencies above 20,000 Hz. For example, x-rays.Grade 11 Physics
Who is the scientist who discovered ultrasonic waves?
Francis Galton is credited with discovering ultrasonic waves in 1893. He observed that high-frequency sound waves could not be heard by the human ear but could still be detected by certain animals.
How many different types of sound waves are there?
All sound is the same, just at different frequencies and volume. However sound is often categorised into three groups. Subsonic - Low frequency, below the threshold of human hearing. 25 hertz or less. Audible - Any sound a normal human being can hear. 25 Hertz - 18 Kilo Hertz. Ultrasonic - High frequency sound, above the threshold of human hearing. 18 Kilo hertz and above. It should be noted that some animals such as dogs and bats can hear much higher frequencies than humans. Also note, the upper limit of human hearing varies from person to person, and decreases with age. 18 - 18.5 kilo hertz is normally the upper limit for most people.
What are high-frequency sound waves that visualize a structure as they strike tissues of different densities in the human body called?
ultrasonography
How are sound and waves different from electromagnetic waves?
they are different because these waves can travel through empty space
What does contrast electromagnetic waves with water and sound waves mean?
It means explain how electromagnetic waves are different than water and sound waves.
Cite example of animals that uses sound waves?
i have nothing
