Final answer:
The Precision Approach Radar operates in the frequency range of 2700-2900 MHz. Calculations of the wavelength for AM radio frequencies (540 to 1600 kHz) and FM radio frequencies (88.0 to 108 MHz) are based on the speed of light and the respective frequency values.
Step-by-step explanation:
The Precision Approach Radar (PAR) frequency range is option B) 2700-2900 MHz. PAR systems are used in aviation to provide guidance information to assist in the landing of aircraft, especially under conditions of poor visibility.
As for the calculation of wavelengths for various frequencies, we use the equation c = λ f, where 'c' is the speed of light, 'λ' (lambda) is the wavelength, and 'f' is the frequency. For AM radio with frequencies ranging from 540 to 1600 kHz, and FM radio frequencies from 88.0 to 108 MHz, the wavelength ranges can be calculated using this formula.
AM Radio Wavelengths
-
- For 540 kHz, λ = c / f = 300,000 km/s / 540,000 Hz = 555.56 meters.
-
- For 1600 kHz, λ = c / f = 300,000 km/s / 1,600,000 Hz = 187.5 meters.
FM Radio Wavelengths
-
- For 88.0 MHz, λ = c / f = 300,000 km/s / 88,000,000 Hz = 3.41 meters.
-
- For 108 MHz, λ = c / f = 300,000 km/s / 108,000,000 Hz = 2.78 meters.
