The speed of waves

Extracts from this document...

Introduction

Physics coursework-The speed of waves Planning Aim: The aim of this experiment is to gain results by dropping a water container from different heights (amplitude) to see which height can get the fastest wave. Method: As the container is dropped I will start the stopwatch. Then as the waves in rebounding back onto the side it started on I will stop it and record this time. I am going to do these three times to gain an average of the results. To calculate the speed I am going to do this equation: Speed = distance/time taken That is how I am going to be able to calculate the speed of the wave. Variables There are many other things that can make the speed of the wave differ. ...read more.

So I predict that by changing the depth of the water in 10-ml intervals I will get more accurate, helpful, results. I will find out if I am right after I have concluded my preliminary work. Apparatus ? Water container ? Ruler ? Water ? Pencil ? Paper ? Measuring cylinder Results The results I've gained I've put into a table, which I show below. /////// Attempt 1 Attempt 2 Attempt 3 Attempt 4 Attempt 5 AV Height 2 2.5 2.3 2.6 2.4 2.1 2.3 Height 4 2.3 2.4 2.4 2.4 2.1 2.3 Height 6 2.4 2.6 2.5 2.3 2.1 2.3 Height 8 2.7 2.5 2.6 2.3 2.1 2.4 Height 10 2.5 2.4 2.3 4.2 2.3 2.7 ANALYSIS When my graph is looked at its clear to see that the gradient of the line doesn't show any particular increase in gradient. ...read more.

Conclusion

The graph shows a smooth curve, which suggest to me, and anyone reading it, that my prediction was very incorrect. I predicted that if I changed the height at which I dropped the container it would change the speed considerably but it didn't so I was wrong. My conclusion to this experiment would be that the experiment I did didn't really help us to find out the difference in the speeds of waves. So to help us gather better results for this purpose I would suggest another different experiment. I would suggest changing the height of the water. Instead I believe that this would gain much better results. If I had done this experiment I expect that I would have gathered a lot more about the differences in the speed of waves. 1 Oliver Sloggett-Taylor 5M-Investigation into the speed changes of waves ...read more.

    The markers are 15 cm apart, as this gives me ample time to start and stop the clock watch, whilst observing the travelling wave. There is human error, when starting and stopping the stop clock and I estimate that this error is about 0.1 seconds as it is roughly the reaction time of a young person.

    I hope to get at least five readings so that I can makes some suitable conclusions to my investigation. My dependent variable will obviously be the speed of the wave. This is because in this experiment I want to study the relationship between depth and speed and the speed will only change as I change the depth.
