Question 3

Explain the principal difference between amplitude and frequency in the context of sound waves.

6 comments:

  1. Amplitude is the physical strength of a wave. Frequency is the number of cycles completed by a wave in a certain time interval. When I think of amplitude, I think of a life line. When the heart is beating and is strong you can see a bigger wave. When someone has died their life line is flat and there is no more change.

  2. The main difference between amplitude and frequency is the fact that frequency measures the time of the sound waves completed in a given time. In other words, it measures how many times a complete wave is completed in time. The amplitude is how strong the sound wave is. The amplitude depends on the air. The amplitude doesn't really measure the wave cycles in times, it measures the strength or energy.

  3. Amplitude is the volume of the sound or how loud it is.The pitch is related to the fequency: it tells us if it's either a low tone or high tone.

  4. amplitude is loudness and the strength of the incomeing wavelength which are either high or low. frequency is the number of repetitions (per second)in a wave length. they are difrent because amplitude is loud frequency is pitch which is the level at which wave length is at.

  5. The difference of frequency and amplitude. frequency refers just to the vibratin of the wave in given amount of time, and amplitude measures the physical strenght of the sound wave.

  6. Well, in the text it states Frequency is the number of vibrations or cycles the wave completes in a given amount of time, whereas Amplitude is a measure of the physical strength of the sound wave. Thus, the overall difference is that frequency is just like its name how "frequent" a wave completes a cycle and Amplitude is how strong the sound wave is like you can think of an amplifier on a electric guitar. On an amplifier, that demonstrates on loud (the strength of a guitar is) through the pounding bass and beats coming from it.
