What are the different ranges of frequencies?

What is Nigeria frequency?

For the purpose of frequency allocation, the world is divided into three regions. Nigeria falls within Region 1. Article 5 of the Radio Regulations deal with these frequency allocations which have been made from 8.3KHz to 300GHz. It is mandatory for all administrations to adhere to these allocations.

What is VHF and UHF frequency range?

UHF stands for “Ultra High Frequency” while VHF stands for “Very High Frequency.” UHF can range from low band (378-512 MHz) to high band (764-870 MHz) while VHF ranges from low band (49-108 MHz) to high band (169-216 MHz).

What range of frequency that most humans can detect?

Under ideal laboratory conditions, humans can hear sound as low as 12 Hz and as high as 28 kHz , though the threshold increases sharply at 15 kHz in adults, corresponding to the last auditory channel of the cochlea. The human auditory system is most sensitive to frequencies between 2,000 and 5,000 Hz .

What is the range of harmful frequencies?

The most dangerous frequencies of electromagnetic energy are X-rays, gamma rays, ultraviolet light and microwaves. X-rays, gamma rays and UV light can damage living tissues, and microwaves can cook them. X-rays have wavelengths ranging from .001 to 10 nanometers, or billionths of a meter.

What is the range of frequencies?

Frequency Range is the actual span of frequencies that a monitor can reproduce, say from 5 Hz to 22 kHz. Frequency Response is the Frequency Range versus Amplitude. In other words, at 20 Hz, a certain input signal level may produce 100 dB of output. At 1 kHz, that same input level may produce 102 dB of output.

What is your range of frequency that humans can hear?

The commonly stated range of human hearing is 20 to 20,000 Hz . Under ideal laboratory conditions, humans can hear sound as low as 12 Hz and as high as 28 kHz, though the threshold increases sharply at 15 kHz in adults, corresponding to the last auditory channel of the cochlea.
