Want this question answered?
I had to use an eyewash after the sand blew in my face.
Energy changes the frequency of things. Specifically, the higher the energy, the higher the frequency.
FM signals travel as changes in the frequency of the wave.ANSWER: DEFINITELY not frequency remains the same.The duty cycle changes.It definitely IS the the frequency which changes. It changes at the same rate as the frequency of the modulation.It can be demodulated with a frequency discriminator. If the frequency remained constant and its "duty cycle" changed, the discriminator wouldn't demodulate it.
the wavelength changes when the frequency changes if the wavelengths are smaller and thinner then the frequency is high, when the frequency is slow then the wavelengths is larger and wider. if the frequency is constant then the wavelength is a normal size
what would be an observable change in sound when the frequency changes
what would be an observable change in sound when the frequency changes
Using an eyewash that is produced to be used as such is safe, if used according to the directions. Homemade eyewashes may be harmful. It is always best to use an approved eyewash.
If you change sound's frequency and hold the velocity constant, the sound's wavelength also changes. If you change sound's frequency and keep the wavelength constant, then velocity also changes.
For an eyewash solution, the measure would be one tablespoon of boric acid per one quart of sterilised water. (do not mistake deionized or distilled water. it must be sterile.)
The pitch. The higher the pitch, the higher the frequency.
Abrupt changes in the frequency cause mostly by abrupt variation in load is frequency scintillation.
