    Please sir, continue and give us more questions throughout physics topics.

    Hi Sir, why did you draw the 2 amplitudes, where did you get the 41mm from and why did you multiply this by 2? (all for the first question). Please let me know. Thanks

      the wavelength is from one peak to another. The diagram only showed half a peak and there is only one wave

    bruh this came up on my end of years a couple months ago and now I’m finding this

    hey sir deez is asking why did you draw the 2 amplitudes, where did you get the 41mm from and why did you multiply this by 2? (all for the first question). Please let me know. Thanks, sincerely deez nuts

      41mm is from the ruler (the distance between the peak and the trough of the wave) - I did not draw the amplitudes, the are arrows to point to the measurements on the ruler! This is only half the wavelength because the wavelength of a wave is the distance from peak to peak (which must go past a trough in the middle). Thank you hassanhamze_14 for explaining in the earlier comment!

    Can you say where the 41 and the x2 came from

      He drew the amplitude to find 41mm on the given picture of where the wavelength starts and where it ends

      And he got the 2 from where the amplitude started
