What is the difference between amplitude and frequency?

Amplitude is the positive and negative peak of the signal while frequency is the no of repetition of the signal in a unit time. We increase the amplitude of our voice signal by shouting loudly while we increase the frequency of our voice signal by speaking faster.

Let me describe the concept in literary way, so that you can remember.

you must heard the two words "amplification or amplifier" and "frequent" in general talks,right.

generally Amplification is used in terms of gaining something , in terms of sound it is used for gaining loudness.

similarly frequency comes from word frequent..............frequency means how frequent some thing is happening.

but when you are asked how frequent for any thing, your answer will be associated with some time as well.

for example :

how frequent do you go to sunil?

you answer:may be once in a week, that's it.

so here your frequency is once per week or 1/week.

generally when frequency is asked with respect to ossilating body or waves, the expected answer is how many times a second, as sec is the SI unit of time.

so standard definition of frequency is number many oscilation per second.

and Amplitude is the max displacement from the mean or stable position of the oscilating body.

want to explain little more.........but had to stop for the time being for some urgent work.

Seen a pendulum? Where is its bottom when it is at rest? At the center, right? Now give it a little push and let it keep swinging to and fro, and observe it.

See how far "the bottom" is going before returning? That "how far" is the Amplitude.

Now, take a stopwatch or normal watch, and count the "number of swings" the pendulum is making in one minute. Let's say the count is coming to be 100. Divide 100 by 60 (because 1 minute = 60 seconds). The quotient you'll get is frequency. 

So, you see the difference?
