Can a high frequency carrier wave travel longer distance than low frequency carrier wave?

High frequency radio waves over ~100 MHz will usually travel only in a straight line - hence these applications are called 'line of sight'.
Waves of lower frequency, say 500KHz to 30MHz (rough values only) are bounced off the ionosphere and can travel round the world.
Waves of very low frequency, 10 KHz to 20KHz, can penetrate sea water, and are used to communicate with subs. But they are of such low frequency that they can carry no effective modulation other than ON or OFF. But they can do a job that nothing else can do.

AM carrier waves have relatively low frequencies they can travel quite a distance why?
They are reflected round the curve of the Earth off layers in the atmosphere which act as mirrors (the ionosphere).
Do the two terms wave speed and wave frequency refer to the same thing?
No, frequency is the function of peak/trough pairs per unit time. Speed is the measure of how long it takes to travel a given distance.
Will a longer pendulum swing faster than a shorter one?
no the bob on the shorter one has less distance per period to travel
Do waves with a shorter wavelengths travel faster than waves with longer wavelengths?
The physical length, short wavelengths are shorter than long wavelengthsThe frequency, short wavelengths are higher frequency than long wavelengthsThe energy per photon, short wavelengths have more energy per photon than long wavelengths
Can rf can travel in vacuum?
If you mean radio-frequency, yes, all electromagnetic waves can travel in a vacuum.
What does it mean to travel at 60 miles per hour?
It means that if you travel for an hour you will have covered a distance of 60 miles. If you travel for a longer or shorter time you will cover a proportionally longer or shorter distance.
How do you find wavelength when distance is given?
Wavelength = speed divided by frequency. Speed = distance divided by time. Therefore: Wavelength = distance divided by (frequency x time). You therefore need to know the frequency of the wave and the time it takes to travel in unit time.
Can you have a radio signal underground?
Yes, you can however the distance that a signal may be travel depends on the power and frequency of the signal. For signals at the same power a lower frequency signal will travel further.
How far does a high frequency sound wave travel going to the moon?
well, what is the distance in kilometers and wher is it from.
Why do planets further from the sun take longer to orbit?
They have a greater distance to travel
What is the distance between Charlottesville VA and Basye VA?
The shortest distance is 78.4 miles, but that takes longer to travel.
Why is the distance people have to travel to get somewhere often longer than the actual distance between two places?
It is because the distance you have to travel between to places never have a straight path from point to point.
IF the frequency is maximum then the signal will far awy or near?
higher frequencies attenuate more the further distance they travel.
If the wavelength of light increases the frequency?
As the wavelength increases, frequency decreases. A wavelength is the distance from, say, a crest to a crest, or perhaps a trough to a trough. Frequency is essentially how many waves or how many cycles of a wave there are per unit of time, and we usually apply the term cycles per second or Hertz (which means cycles per second) to it.Wavelength is the physical distance the wave will travel as a single cycle of that wave occurs. And wavelength is a function of both frequency and of the speed of propagation of that wave. In any case, a longer wavelength is associated with a lower frequency. Increasing (lengthening) the wavelength decreases the frequency.
Why do low frequency waves travel longer distances?
High frequencies are more damped by air than low frequencies.
What is the wavelength of an electromagnetic wave that has a 1 hz frequency?
The distance light takes to travel in a second (just less than 30000000metres).
What is the purpose of carrier signal in modulation?
Carrier signal is of high frequencies, it gives strength to the original signal because original signal cannot travel long distances so it needs to be strengthen a bit for transmitting. The carrier signal is a high frequency signal, called an RF. Radio Frequency signal, it is to high for the human or animal ear to detect it, so its outside the audible spectrum and can easily be transmitted over the air to receivers that is tuned to receive that frequency and detect any modulation on that signal.
