What electromagnetic waves can be used for communication?
Radio waves are used for communication such as television and radio. Radio waves are transmitted easily through air. They do not cause damage if absorbed by the human body, and they can be reflected to change their direction. These properties make them ideal for communications.
Which wave has highest frequency?
Gamma rays have the highest energies, the shortest wavelengths, and the highest frequencies. Radio waves, on the other hand, have the lowest energies, longest wavelengths, and lowest frequencies of any type of EM radiation.
Does the heart emit electromagnetic waves?
The heart is the most powerful source of electromagnetic energy in the human body, producing the largest rhythmic electromagnetic field of any of the body’s organs. This field, measured in the form of an electrocardiogram (ECG), can be detected anywhere on the surface of the body.
Does the heart send messages to the brain?
Yes, the human heart, in addition to its other functions, actually possesses a heart-brain composed of about 40,000 neurons that can sense, feel, learn and remember. The heart brain sends messages to the head brain about how the body feels and more.
How the heart communicates with the brain?
Research has shown that the heart communicates to the brain in four major ways: neurologically (through the transmission of nerve impulses), biochemically (via hormones and neurotransmitters), biophysically (through pressure waves) and energetically (through electromagnetic field interactions).
How does the heart produce an electromagnetic field?
Second, the heart produces a significant electromagnetic field with each contraction due to the coordinated depolarization of myocytes producing a current flow. Unlike the electrocardiogram, the magnetic field is not limited to volume conduction and extends outside the body.
Does the brain have an electromagnetic field?
McFadden proposes that the digital information from neurons is integrated to form a conscious electromagnetic information (cemi) field in the brain. Consciousness is suggested to be the component of this field that is transmitted back to neurons, and communicates its state externally.
