Remember, they are connected now. Amplitude means height. So, I will know this particular wave signal that this wave signal consists of one – 100 meters long wave of height 2 meters plus one – 150 meters long wave of height 3.5 meters plus etcetera, because when I say 100 meters long way, what I am saying, one way of frequency omega 1. Remember, length, frequency, k are connected. So, I am saying 100 meters long wave means one wave of frequency omega 1 of height A 1 – 3 meters plus another wave of frequency omega 2 of height so much meter. I know that. So, this signal – therefore, I am able to breakdown, where I can correlate the length with the height. It means it consists of so much waves of so much length of so much height.

Length means period means frequency. So, you see, I could get frequency this side
