42.8 kHz is hardly a light frequency. In fact, it's hardly much of a radio frequency.
It has a wavelength of over 4.3 miles, and is capable of communicating only very
low rates of information, like the time code to the 'atomic' clock in your house,
four times a day.
For comparison, the longest wavelength of visible light is about 0.000026 inch .

What is the frequency of tsop 1738?
38 kHz
What is the frequency of the second harmonic if the fundamental frequency is 1000 Hertz?
If the first harmonic of 1 kHz is 2 kHz, then the second harmonic is the odd order harmonic of 3 kHz.
What is the frequency of simple IR Transmitter?
40 kHz
What is the minimum sampling rate if the input frequency is 3 kHz?
According to the Nyquist theorem, the minimum sampling rate must be at least twice the maximum frequency of the input signal to avoid aliasing. Therefore, if the input frequency is 3 kHz, the minimum sampling rate should be 6 kHz.
What would be the minimum sampling interval needed for reconstructing a signal where the highest frequency is 1 kHz?
The Nyquist frequency for a signal with a maximum bandwidth of 1 KHz is 500 Hz, however that will lead to aliasing unless perfect filters are available. The Nyquist rate for a signal with a maximum bandwidth of 1 KHz is 2 KHz, so the answer to the question is 2 KHz, or 500 microseconds.
What is the minimum sample rate required to record a frequency of 96 kHz?
The minimum sample rate required to record a frequency of 96 kHz is 192 kHz. This is because according to the Nyquist theorem, the minimum sampling rate must be at least twice the highest frequency in order to accurately reconstruct the original signal. So for a frequency of 96 kHz, the minimum required sampling rate is double, which equals 192 kHz.
The lowest frequency of a signal is 10 kHz the highest frequency if 1 MHz what is the bandwidth?
BW = (1 MHz - 10 KHz) = (1,000 KHz - 10 KHz) = 990 KHz
What is the frequency of this am radio wave in hertz when An AM radio station broadcasts news at 687 kHz?
For any wave, frequency x wavelength = speed (of the wave). In this case, convert the kHz to Hz, then divide the speed of light by this frequency. The speed of light should be in meters/second. The answer will be the wavelength in meters.
If a radio station is tuned at 1600 kHz what is the image frequency?
Assuming that the receiver uses a high-side local oscillator and an IF of 455 KHz, the image frequency is 910 KHz above. When tuned to 1600 KHz, the image frequency would be 2,510 KHz.
What is the frequency deviation if an 2.5 volt 1 khz signal frequency modulates the carrier to cause frequency deviation of 4 khz on increasing the modulating voltage to 10 volts?
If 10 V input causes a frequency shift of 4 kHZ then 2,5v causes a freuency shift of 1 kHz. The input signal frequency of 1 kHz is irelevant.
What is the period of a clock waveform whose frequency is 500 kHz?
The period of a waveform is the reciprocal of its frequency. For a clock waveform with a frequency of 500 kHz, the period can be calculated as 1 / 500 kHz = 2 microseconds.
What is the frequency of the trovan microchip?
Trovan 128 Khz and ISO 134 Khz
What standard unit is used express frequency?
The standard unit used to express frequency is the hertz (Hz), which is defined as one cycle per second. Frequencies can also be expressed in kilohertz (kHz), megahertz (MHz), and gigahertz (GHz) for larger quantities, where 1 kHz equals 1,000 Hz, 1 MHz equals 1,000,000 Hz, and 1 GHz equals 1,000,000,000 Hz.
What is the period of the wave motion for a wave with a frequency of 0.50 kHz?
Period = reciprocal of frequency = 1 / (500) = 0.002 second
What is the frequency swing of an FM broadcast transmitter when modulated to 60 percent?
The maxium frequency swing in FM is ± 75 kHz so 75 kHz x 60% = ± 45 kHz
30 HZ equals how many KHZ?
1 kilohertz=1000 hertz 30 hertz = .03 kilohertz
What is the average am broadcasting frequency?
The standard US AM band is 520 kHz-1,610 kHz. The mean would be at 1,065 kHz.
