20. Interference, Soap Bubble

[@tyh2012]

The soap bubble demonstration and its explanation are spectacular, precise and clear. Or could I say , another Best Physics Teacher, following Prof. Walter Lewis, just one coming from Ethnic Chinese Group. I just wish Chinese interested students could benefit from the knowledge and enthusiasm that Prof. Yen-Jie Lee have been displaying all along in the videos. Thank so much, Prof. Lee !

This lecture is so inspiring and it gives very clear intuition. I can see bubble as a more beautiful thing than ever! Thank you!

Not only soap bubbles, also oil (gasoline) stains floating on water, for example. They have the same effect because the oil that floats on the water varies in depth, so light of different wavelengths shines through at different points.
