Thanks alot for such a helpful video, perfectly explained, excellently demonstrated. Helped me alot in understand the reflection and refraction of water waves in a ripple tank. Amazing work guys!
yes yes mmmm yes I liked this graphical representation very much indeed mmm, thank you for the contribution to the wonderful youtube community my friend!!
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.
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.
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 :)
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?
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.
thank you very much sir.good luck!from sri lanka
You are welcome
Today I'm gonna have a physics test. This will help me a lot. Thank you
@Javion Archie good luck I guess 😅
I’m having that physics test tomorrow, well technically today lol
@@clearchaos good luck you got this 🙌🏼💪🏽
@@itsyuki9626 it's 3 years now
How was your test? 😊
@@pkpk9513 it was okay 😂. Aww thanks for asking sweetheart ✨😌
Wow this is so clear and good explaining. Thank you keep going. GOOD LUCK!!!!
Thank you so much Warna :)
@@LasecGroup your welcome 😊😊
Man, i'm very happy i have found you. Thanks a lot.
Only a pleasure :D
@@laseceducation7933 Thanks a lot. We want to discuss arabic translation and voice over your videos. Would you please send your email 🙂
Thank you for this.
This video helped me a lot to clear my concept.
thank you very much for this video, very helpful, and beautifully made
Thank you for the lovely feedback Craig :)
Thank you very much, very helpful for study

Thanks for the feedback Anas. We're so glad you enjoyed it :)
Loved your Video 💖💖
Your Splendid Effort to make this Video needs to be Appreciated 🤩😘💖
What a lovely comment Anees. Thank you so much we really appreciate it 😊
@@laseceducation7933 Thx💟
Wow amazing in practicals it help me a lot thanks for your vedio keep it up😘😘😘
Thank you so much Hafiz!
It was good, right according to the syllabus of every grade and for high school specially...👍
yes yes mmmm yes I liked this graphical representation very much indeed mmm, thank you for the contribution to the wonderful youtube community my friend!!
deserve more than these likes and comments,, excellent job sir!
It’s amazing and helped me a lot! Thank you sir!
Pleasure 😊 Thank you for taking the time to comment!
Great video, but why does it look like the circular waves are moving towards the source, not away?

@@laseceducation7933 Thank you very much for your quick answer!
It was cool man , I like that , by seeing this video my concepts are very cleared . Thanks A lot
Thank you soo much. I missed that theory from the clz. So that was really helpful for me to do my self studying.😊😊😊
Thank you very much for this vedio🙏
Thank you so much for the video, it was so simple yet so educational. Loved it 🖤🖤
Thanks Sir For this Experiment
Its a pleasure :)
Great 😎😎
Nice demonstration. Well explained.
Very educational video, well done!
very nice
now i know how to make waves . Nice
Thank you so much
Fantastic.....helps me in teaching about Waves in Physics.
Hi Bernard :) We are happy to hear that this video has been of great assistance in learning Physics :D
thanks its help me alot
It is a pleasure!
Very nice.
awesome.very useful.thanks
Thank you so much 😇.
It is nice
Good work
Very well explained 💙
A wonderful job! Really helped me prepare for my Practical.
Thank u sir
Nice video
Thank you Dario :)
nice tutorial
Thank you Noor 😊
Good and very informative, Thanxs a lot
Amazing!
Thanks!
Great. What would we see if the freq increased in refraction experiment? Thanks
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.
@@laseceducation7933, Thank you, but what I wonder is, when we increase the frequency, does the angle of refraction change?
Thanks
Awesome
Thank you Mohamed 😊
@@laseceducation7933 i learned lot sir, Thank you
Thanks !
thank you
Thanks a lot may god bless you !!..
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 :)
Thanks Nicole, we'll keep that in mind for future videos!
Nike
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
Thank you so much.
Are the ripples energy entangled?
Fantastic
thnkx a lot sir

What does a stroboscope do
superb
Nice
I love education
