Homework Help Overview

The discussion revolves around the representation of a sound wave in a graph format, specifically questioning whether the graph accurately depicts sound waves in a medium. The subject area includes wave physics, focusing on sound waves and their characteristics.

Discussion Character

  • Exploratory, Conceptual clarification

Approaches and Questions Raised

  • Participants express uncertainty about the correctness of the graph representing a sound wave, with some questioning the nature of sound waves compared to electromagnetic waves. Others suggest analyzing the graph as a sine wave and identifying parameters to match the wave's characteristics.

Discussion Status

The discussion is ongoing, with participants exploring different interpretations of the graph. Some guidance has been offered regarding the sine wave representation, but there is no consensus on the accuracy of the graph itself.

Contextual Notes

Participants are grappling with the definitions and characteristics of sound waves versus other types of waves, indicating a potential misunderstanding or lack of clarity in the graph's representation.

I had today an exam.

I that exam this graph they said represent a sound wave. Is this graph correct representing a sound wave in a medium? My interrogation is about y/m as a function of x/m!

Thanks in advance!

No help! Is this a nonsense question?
 
well, i guess no, it's not right, as sound waves are compressive waves, not like electromagnetic that look like that(or more or less like that).
 
It looks like a sine wave to me. So y/m=Asin(kx/m). Find A and k to reproduce the peaks and zeros of the wave.
