Doubling the frequency of a wave source (without altering the medium) doubles the speed of the waves. Don't be fooled. Yet doubling the frequency only halves the wavelength; wave speed remains the same. To change the wave speed, the medium would have to be changed.
The data convincingly show that wave frequency does not affect wave speed. An increase in wave frequency caused a decrease in wavelength while the wave speed remained constant. Rather, the speed of the wave is dependent upon the properties of the medium such as the tension of the rope.
The amplitude decreases with an increase in the frequency of a wave. The amplitude increases with an increase in the frequency of a wave.
The data convincingly show that wave frequency does not affect wave speed. An increase in wave frequency caused a decrease in wavelength while the wave speed remained constant. The speed of the waves was significantly higher at higher tensions.
In most cases, frequency affects the speed of waves. When talking about light it doesn't because when the frequency of a light wave changes, the wavelength changes so that it will always move at a constant rate in a specific medium.
The Greeks realized that sounds which have frequencies in rational proportion are perceived as harmonius. For example, a doubling of frequency gives an octave. A tripling of frequency gives a perfect fifth one octave higher. They didn't know this in terms of frequencies, but in terms of lengths of vibrating strings.
A close whisper is 100 times more intense than the threshold of breathing. A close whisper is 10 times more intense that normal breathing.

The amplitude and the frequency of a wave are independent of each other. The amplitude and the frequency of a wave are equal. The amplitude increases with an increase in the frequency of a wave.
Frequency and period are actually opposites. While period is measured in seconds per cycle, frequency is measured in cycles per second. Consider our wave with a period of 2 seconds. Since the wave completes one cycle every two seconds, then its frequency is one half or 0.5 Hz.
So going up an octave in pitch means doubling the frequency. There is another observation we can make about the second harmonic.
Since the energy goes up as the frequency increases, the energy is directly proportional to the frequency. When the energy increases the wavelength decreases and vice versa. That is, energy in inversely proportional to wavelength. In short, a photon can be described by either its energy, frequency, or wavelength.
If you decrease the frequency with the voltage constant, hysteresis loss increases. That is, at reduced frequencies there is no enough path for the hysteresis current to flow in the core thereby generating heat.
So if frequency increases, the secondary voltage or emf increases. And secondary voltage decreases by the reduction of supply frequency. Also with high frequency the magnetizing current becomes low and with low frequency the magnetizing current becomes high.
And as wavelength increases, the frequency decreases. Since c never changes, and EM waves MUST travel at c, then any increase in frequency results in an automatic shortening of wavelength. And as wavelength increases, the frequency decreases.
Therefore, if you halve the frequency the wavelength will double.
The particles available to be involved are essentially reduced, making the remaining particles absorb the existing energy of this wave. The additional energy causes the increase in frequency, since the period of the wavelength has been reduced.
Shorter strings have higher frequency and therefore higher pitch. Tension refers to how tightly the string is stretched. Tightening the string gives it a higher frequency while loosening it lowers the frequency. When string players tighten or loosen their strings, they are altering the pitches to make them in tune.
Spreads out. Example: Sound gets quieter or light gets dimmer the further you are from the source, decreasing the amplitude as the wave spreads out. The wavelength period and frequency do not change.
