Wave in an Elliptic Pond

[@sophieward7225]

Fantastic! Even knowing what would happen to a wave centered at a focus point I was still amazed

[@osrevad]

Could you do one where the wave is centered at one of the foci? I know what the start and end would look like of course, but it would be great to see what happens in between.

Mesmerizing.

Very good

[@maximtiburziano872]

Can I ask you the code? 🥺

[@doubledonut9313]

the code is quite simple. but figuring out yourself would be very please. I can give you some steps: 1. find the slope of the ellipse 2.find out what do reflection do to the direction of the ball travel 3.find out what is the general case of the reflection 4.use quadratic formula to find the next interception

@@doubledonut9313 thanks you. But I already did it, not on Manim, but on Desmos. And the last one is a different reality, and It's way more limited. Manim for me is VERY difficult
