Introduction

Waves coursework

What is the investigation about?

The Investigation was about how waves travel. Water waves travel more slowly in shallow water in deeper water. This is can be shown by placing a flat Perspex or glass plate in a bottom of a ripple tank.

       As the water waves pass into the shallow boundary, the direction of the waves  

What could I change?

We could change the volume of the water, we could change the temperature of the water, we could change the size of the tray, we could have a set time, we could have

What will I change?

Question

If we pushed the tray harder, will it produce more waves?

Conclusion

What our results tell me

The results tell me that the bigger the force the longer the waves will last.  

Was this what I expected to happen,    

Yes, because we all know if we push things harder, or make something quicken up, then the product we are working with will produce more of a frequency. So this works with waves. So what I have said here corresponds to my question,      

How Accurate were we?

We were not 100% accurate. The water kept spilling over the top. So the volume kept dropping. We never really stopped the time when we had to, partly us and the stopwatch fault.                

Could we make the method better?

Yes I think we could have. Even though we made an effort with a preliminary experiment we could have done another one  and has got some results.

  1. Velocity of a wave in a tank at varying depths of water

    was filled with water up to a depth of more than 4cm the waves that were generated would cause water the surge over the top of the tray and onto the floor. This not only disrupted the wave, it caused the water level in the tank to fall.

  2. Sound waves

    The blue color indicates the blood moving away from the transducer and the red indicates the blood which is flowing towards the transducer. Through this, it is possible to identify the abnormalities of blood flow into the heart such as leakage of blood through values.

  1. Spring Investigation

    Observations I will make sure it is a fair test by accounting for all the factors that will affect the stretching of the spring. . Type of wire . Size of the load . Length of wire . Cross-sectional area of the wire .

  2. Solar Panel Investigation

    It can be considered that as the distance is changed, so the voltage will be altered as well. As the panel is moved further back away form the light, less light will hit the panel so less voltage will be generated. The inverse square law can explain this further.
