Complete "3 - Waves HOMEWORK"

Use the annotated SLIDES in the content library to help you if you are stuck - Use Slides 16-17 that go through three examples so you know what you have to do.

If you are still stuck, for this week, until we know what day Physics clinic will be, please check with each other, or find me in the staffroom for some help.

As a reminder;
  • Number of waves;  Waves can be counted 'peak to peak' as '1 wave', if it not clearly a whole wave, you may have to estimate as a decimal (e.g. 'peak to trough' is half (0.5) of a wave, or 'midpoint-up to peak-back to midpoint' is also 'half (0.5) of a wave')
  • Width of screen;  count the boxes across the grid.
  • Wavelength; You have two ways to do this - 1) the number of grid boxes between two adjacent peak, or, if its not a clear whole number (or if you can only see part of a wave on a very stretch out wave), do "width of screen / Number of waves seen", e/g. " grid of 8 squares / 2 waves on the grid = 8 / 2 ==> wavelength = 4"
  • Amplitude = The 'height' FROM THE MIDPOINT of the wave - so you can find it out by counting (vertically) the grid squares between peak and trough (estimate to 1dp if its not obvious) but make sure tou HALF this value to find the amplitude.
