It's called ultra high frequency, of UHF.
The terms 300 MHz and 300 GHz refer to specific frequencies in the electromagnetic spectrum. MHz (megahertz) denotes millions of cycles per second, while GHz (gigahertz) denotes billions of cycles per second. Thus, 300 MHz is a frequency typically used for FM radio and some television broadcasts, whereas 300 GHz falls within the millimeter wave range, often used in advanced communication technologies and radar systems. The difference in frequency affects the wavelength, propagation characteristics, and applications of the signals.
It seems you are talking about radio waves. The wavelength (40 m) multiplied by the frequency (7 million / second) must equal the speed of light (300 million meters/second). It seems that in this example numbers, either the wavelength or the frequency, or both, are not expressed with a great accuracy. For example, if 40 meters is exact, the frequency would be close to 7.5 MHz.
The frequency of a wave is inversely related to its wavelength. Using the speed of light (approximately 299,792,458 m/s), the frequency (f) can be calculated using the formula ( f = \frac{c}{\lambda} ), where ( \lambda ) is the wavelength. For a wavelength of 1 meter, the frequency would be about 299,792,458 Hz, or approximately 300 MHz.
Not possible ! MHz is a measure of frequency, km is a unit of distance - while gigabits is a quantity of memory.
500,000 Hz is equivalent to 500 MHz, as 1 MHz is equal to 1,000,000 Hz. To convert from Hz to MHz, you divide the frequency in Hz by 1,000,000. Therefore, 500,000 Hz divided by 1,000,000 equals 0.5 MHz.
Ultra high frequency designates electromagnetic waves with frequencies between 300 MHz and 3 GHz or 3,000 MHz.
30 MHz to 300 MHz
30 Mhz - 300 Mhz
Ultra high frequency designates electromagnetic waves with frequencies between 300 MHz and 3 GHz or 3,000 MHz.
The frequency can't be 30 Mhz 30 Mhz is a ham radio frequency but to calculate the wavelength, devide 300 by the frequency in Mhz that will give you 10 meters (300/ƒ)
LF - Law Frequency (10 to 300 KHz)MF- Medium Frequency (300 to 3000 KHz)HF- High Frequency (3 to 30 MHz)VHF- Very High Frequency (30 to 300MHz)UHF - Ultra High Frequency (300 to 3000MHz)
VHF = "Very High Frequency" Formally, radio frequencies from 30 MHz to 300 MHz. (Wavelengths between 1 meter and 10 meters)
The frequency can range between 300 MHz and 300 GHz.
Microwave light has a frequency range of approximately 300 MHz to 300 GHz.
Microwaves are electromagnetic waves with wavelengths ranging from lambda = 1 mm to 1 m, that are frequencies between f = 300 MHz and 300 GHz.
300 MHz: λ = about 3.278 feet.
Wavelength is calculated in MHz not Hz, and the formula is Wavelength = 300 / MHz
