This shows the comparison on how the frequency does not affect the speed of waves. As you can see in the picture, when you increase or decrease the frequency, it changes the number of waves per second. If it is increased, the number of waves per second is more than when you decrease. Even though this is correct, it does not affect the speed of the wave.
Tension does affect the speed of waves. By changing the tension, it affected the graph or rather the speed. Compared to the normal screenshot, the time taken for this wave to reach the end is longer.
Amplitude does not affect the speed of waves. When the amplitude of the wave changes, the only sign of change is in the height of the wave. So, even if you change the wave the time taken for the wave to reach the end is the same. It is seen clearly in the screenshot that the time taken is still 1.69s.

For the part on frequency affecting the waves, your screenshots did not capture the first wave. So it's not possible to make a conclusion based on the two screenshots.

ReplyDeleteI agree to the above statement but does the above mean that the wave speed has changed?
