It is nice Good work

[@MultiSuperGuide]

Great video, but why does it look like the circular waves are moving towards the source, not away?

[@laseceducation7933]

Hi @MultiSuperGuide, thanks so much for your comment and question! Yes, the video appears to be doing so, however, it will absolutely be going away in real-time/real-world use and application of the ripple tank. The camera's shutter speed and the video are deceiving to the eye. It is 100% travelling away from the source and not towards it.

Are the ripples energy entangled?

[@fatimajaved4751]

Good and very informative, Thanxs a lot

[@vkdem]

Great. What would we see if the freq increased in refraction experiment? Thanks

[@laseceducation7933]

Naturally a higher frequency will decrease the wavelength so the bands in the projection may be seen to be closer together before hitting the prism plate BUT the typical refraction pattern will be seen as the wave front hit the prism - the speed of the waves will change (decrease), the wavelength will also decrease and the frequency will remain constant.

[@vkdem]

@@laseceducation7933, Thank you, but what I wonder is, when we increase the frequency, does the angle of refraction change?

[@nicoless625]

Wonderful examples! Only suggestion is to give more time for viewers to observe the reflection and refraction patterns. A quick rewind fixed that on my end :)

[@laseceducation7933]

Thanks Nicole, we'll keep that in mind for future videos!

What type of motor is it? Anyone? Thank you.

Hi Kelly :) It is a standard 3V motor soldered onto wires to fit purpose to the ripple tank and speed controller. www.laseceducation.com/motor.html

What does a stroboscope do

[@rizwanhaider3222]

Iis interesting 👍

[@rawahajunaid2530]

superb

[@johnjordan3552]

Sir in school; with a stroboscope containing one slice, if the water waves look motionless we say that the frequency of the stroboscope equals to the frequency of the waves. However it can also be that Fs=n×Fw where n is an integer, meaning when the stroboscope goes one tour the waves do full oscillations n times (where n is an integer). I told this to my teacher but he denied it, even when I told him about the effect that occurs when a camera's capture rate is a factor of the rotating frequency of a chopper(exact equation depends on the number of slices/blades on the device and the chopper of course). Is that true? And why?

[@analogplanet9675]

Good thinking. You can treat the stroboscope as a "camera" taking pictures at a certain rate. This process is called "sampling" and the effects you describe are called "aliasing". If you take pictures of the wave faster than once per cycle, you will capture images of multiple phases of the wave and see a blurry surface. If you capture images every other cycle, or every three cycles, or every N cycles, you will see the same frozen wave. These spinning wheel stroboscopes are actually somewhat more complicated by the fact that the sampling window is traveling along, but nevermind that.
