Today in science class I watched an amazing video about how waves move when drips fall on water. I found out some really interesting things, it was like I did a real experiment!
If we keep our amplitude constant, and change the frequency, then our wavelength will change too: If the frequency increases, our wavelength will decrease, opposite: Smaller frequency will give us a bigger wavelength. We can observe our wavelength on the graph below the picture – in the axe position. On the other hand, if the frequency is constant and we changed the amplitude, then the wavelength will stay the SAME! However,the position of the crest and trough will just get bigger and bigger.
What I also found interesting was if you put a barrier in the middle of the water space, the waves get slower after they reach the barrier, and even slower when there are two barriers, or slits as it is written in this video.
Good description of your observations. Isn't it interesting that the waves slow down even though they can still go through a slit in the barrier?
