What is noise in physics?
Waves of air that oscillate at a particular frequency. The ear drum picks up these waves, and then the brain interprets them.
How does the human brain perceive infrared sound wave reflections from stationary metal objects?
The term "infrared" refers to electromagnetic waves, not to sound waves.
What is a low frequency wave?
Radio waves are the lowest frequency waves. Next are microwaves, then infra-red waves.
How does frequency apply to periodic waves?
Periodic waves are characterized by a frequency, a wavelength, and by their speed.
What are electromagnetic waves organized by frequency?
the electromagnetic waves are organized from low to high frequency.
REM sleep is characterized by what frequency and what amplitude brain waves?
High frequency and low amplitude.
How can brain waves produced during REM sleep be described?
The frequency of your brain waves during REM sleep are beta (which incidentally occurs during the waking state as well). These are low voltage, high frequency waves.

Waves of air that oscillate at a particular frequency. The ear drum picks up these waves, and then the brain interprets them.
What are the types of brain waves?
From lowest to highest frequency, Delta, Theta, Alpha and Beta
How low or high a sound seems?
Sound is pressure waves travelling through the air. The brain can detect the difference in sound frequency, based on the distance between pressure waves, by the ear which physically responds to incoming sound waves. Volume, frequency and direction are identified, then translated and sent to the brain as electrical signals.

Which waves have lower frequency radar waves or visible waves?
Radar waves have a lower frequency that light waves.The frequency of a light wave is related to wavelength and speed by the equation c = »½. The color of a light wave is also determined by the frequency. The amplitude and brightness are not related to the frequency.
Does a phone cause cancer?
No. There is concern that the radio frequency waves can cause tumors of the neck and brain, but there has been no conclusive research.
