How do waves carry signals?
Waves can be varied (modulated) by either changing amplitude (amplitude modulation AM) or changing frequency (wavelength) (frequency modulation FM). The modulations are used to carry the information signal.
How do you increase the energy of waves?
By increasing its amplitude and/or frequency.
Do the energy of a mechanical wave depends on the frequency of the wave?
Yes, energy transfer for mechanical waves is dependant on frequency as well as amplitude. Energy of electromagnetic waves, however, does not rely on frequency but solely on amplitude.
Does a sound wave with a large amplitude transfer more frequency than a sound wave with a small amplitude?
No it doesn't. The amplitude is the distance of the crest/trough from the rest axis. The frequency is the rate at which the wave "pulsates". If the waves are closer together, then the frequency is increased. If the waves are bigger in width, the amplitude is increased.
Wavelength frequency amplitude and what are the four characteristics of waves that can change?
wavelengh, frequency,amplitude, and wave speed
How are radio and television waves added to em waves?
by changing the amplitude or frequency of the radio waves.

How are radio waves and television signals added to EM radio waves?
by changing the amplitude or frequency of the radio waves.
How are radio television signals added to EM radio waves?
by changing the amplitude or frequency of the radio waves.
What affect if any does frequency have on the amplitude of the waves?
Frequency has no effect on teh amplitude of a wave.
REM sleep is characterized by what frequency and what amplitude brain waves?
High frequency and low amplitude.
What does amplitude measure?
Sound energy travels in waves and is measured in frequency and amplitude
How do you increase the energy of waves?
By increasing its amplitude and/or frequency.
What do tsunami waves carry which is common to all waves?
Wavelength, Amplitude, and Frequency.
Do the energy of a mechanical wave depends on the frequency of the wave?
Yes, energy transfer for mechanical waves is dependant on frequency as well as amplitude. Energy of electromagnetic waves, however, does not rely on frequency but solely on amplitude.
What does fm and am stand for?
AM-Amplitude modulated FM-Frequency modulated Explanation: The frequency and amplitude refer to the width and height of wavelengths in the radio waves that are used to transmit the signal. FM is usually a better signal than AM because the frequency of the waves is less distorted than amplitude.
