Radio Frequency electromagnetic energy- The term radio frequency, or RF, refers to a set of electromagnetic waves that have frequencies between 30 and 300 GHz. These waves are commonly used in short- and medium- range radar. At radio frequencies, most of the Earth’s atmosphere and most of the ground is transparent, so radio waves can be used for a long distance communication. Radio frequency can be used to transmit or to receive information. The electromagnetic waves from radio-frequency energy are categorized as radiation. The waves are emitted by a transmitter and are received by a receiver. Many sources of radio-frequency energy exist: radio broadcasting, radio-frequency identification (RFID), microwave ovens, and radio remote controls are all examples of sources of radio-frequency energy.
RF Radiation and human health- Electromagnetic radiation is commonly emitted from electrical devices such as home appliances and electronic equipment. Some of this energy can be absorbed by humans, while other parts may pass through, and still other parts may be reflected. In general, humans are highly sensitive to electromagnetic radiation. Although scientific data are scarce, many health professionals feel that exposure to RF radiation is harmful to health. Scientists do not yet have conclusive evidence that RF radiation contributes to health problems. However, the World Health Organization (WHO) has listed RF radiation as a possible carcinogen that may be harmful to humans. This is why the federal government implemented regulations for the use of radio-frequency radiation.
Two strings of equal length are attached to an immovable pin at equal distances from the pin. The first string is tuned to vibrate at a frequency of 100Hz. The amplitude of vibration of the second string is 1mm. What is the frequency of the second string?
The physical properties of waves can be described mathematically in terms of a number called the wave number. The wave number is one of the three basic quantities that are used to describe waves. This is the number that relates frequency to wavelength and energy.
Waves carry energy. When a wave travels in a medium its energy travels along with the wave. Energy is sometimes expressed in a different form that is useful for describing waves. It is called energy per unit length or energy per unit time.
If two waves of the same frequency travel through the medium and the waves do not change the pressure then the waves are called constructive. If the waves change the pressure in the medium, the waves are called destructive.
