Sound waves and amplitudes Problem

[QUOTE="happysmiles36, post: 4851919, member: 359374"] I can't answer your first one because I haven't done sound stuff in a long time, however, for question two: Correct: Yes Incorrect: The wave speed in medium Amplitude is a measure of how big the wave is. Wave length is the distance between crest-crest or trough-trough and frequency tells us how many waves are passing a point per second. Bringing in medium and wave speed is kind of unrelated to the question so it in a way shows you don't really know what you are talking about. You can think of it like this. If you look at a sine graph. The amplitude is 1. (The highest it can be is 1, and lowest is -1) However if I change the distance between the waves, the amplitude still stays as 1. This is because frequency and wavelength, doesn't change the "size" of the wave, they affect the distance between two points on a wave. Hopefully I explained that well enough. [/QUOTE]
