Low frequency waves are waves with long wavelengths, by definition, since their cycle is slowly repeated. One example is AM radio waves compared to visible light waves. AM radio waves have a frequency of around 1 MegaHertz (1,000,000 s-1) and are around 500 meters long. In contrast, visible light waves have a frequency of around 500 TeraHertz (300,000,000,000,000 s-1) and are around 500 nanometers long (.000000500 meters).
What else can I help you with?
What kind of radiation do photocopy machines emit and what is the exact wavelength of this radiation on average?
Other than visible light used to scan the original to be copied, some heat, and the kind of very low and extremely low frequency electromagnetic radiation emitted by all electrical devices, photocopiers do not emit radiation.
Is it true that the radiation of photocopier machine is harmful?
No. A photocopier emits light radiation at levels commonly encountered in the industrialized world. That is not harmful. Like all electronic devices, a photocopier emits low frequency, very low frequency, and extremely low frequency electromagnetic radiation, but in amounts similar to other widely used machines. If this level of emission were hazardous, there would be highly visible warning symbols displayed on the machines, and a highly visible epidemic of the hazardous effects. No such symbols are posted on the machines, and no such epidemic has been seen.
What color of light was a highest frequency?
Violet. Recall VIBGYOR. Violet at the high frequency extreme and Red is at the low frequency extreme
Which had lower frequency infrared radiation or red light?
Infrared has a lower frequency.
How are we able to hear thunder?
I believe this is because of extremely low frequency waves (ELF). Like how you can feel the music at a rock concert, i believe this is similar.
What are the forms of radiation?
Alpha, Beta, Neutron, X-ray, Gamma, Neutron radiation, Electromagnetic radiation, Visible light, Infrared, Microwave, Radio waves, Very low frequency (VLF), Extremely low frequency (ELF), Thermal radiation (heat) and Black body radiation.
Which type of em spectrum has the highest wavelength?
The energy of EM radiation depends on its frequency, and the lowest frequency corresponds to the lowest energy. Radio waves are at the low end of the energy and frequency spectrum.
Radiation on tranformers?
Very low frequency.
What is the radio frequency range?
freq range of rf is 3hz (extremely low frequency) to 300Ghz (extremely high frequency)
What type of waves is as big as buildings?
These are medium, low and very low frequency radio waves as well as ultra low, super low and extremely low frequency waves.
Which type of radiation in the electronmagnetic spectrum is the least energetic?
The electromagnetic spectrum is a continuum. The least energetic type of radiation may be found in what is known as "extremely low frequency" radiation (ELF). This is radiation with a frequency in the range 3-30 Hertz. ELF radiation can penetrate seawater and so is particularly useful for communicating with submarines.
Why does electromagnetic radiation have the lowest energy?
Electromagnetic radiation has the lowest energy due to its long wavelength and low frequency. In the electromagnetic spectrum, radiation with longer wavelengths, such as radio waves, carries lower energy compared to higher-frequency radiation like gamma rays.
Which waves in the electromagnetic spectrum have the longest wavelength?
The waves with the longest wavelengths are known as radio waves.
What types of electromagnetic radiation do human bodies emit?
Human bodies emit various types of electromagnetic radiation, primarily in the form of infrared radiation (heat) and extremely low-frequency electromagnetic fields produced by biological processes like nerve impulses and muscle contractions. These emissions are typically very low in intensity and are a natural part of the body's functioning.
What kind of radiation do photocopy machines emit and what is the exact wavelength of this radiation on average?
Other than visible light used to scan the original to be copied, some heat, and the kind of very low and extremely low frequency electromagnetic radiation emitted by all electrical devices, photocopiers do not emit radiation.
What is low frequency radiation called?
LF-RF or low frequency radio frequencies. This spans frequencies from just below the AM radio band through the shortwave radio bands.
Long wavelength and a low frequency is what type of radiation?
This type of radiation would be classified as radio waves. Radio waves have long wavelengths and low frequencies, making them suitable for communication and broadcasting purposes.
