🌊Wave diffraction around Rincon Point, Santa Barbara. Waves are pushing out in all directions but line-up into wavefronts on the open ocean. The wavefront is broken when it meets a corner of land allowing the waves to push out into a new direction forming a new wavefront. pic.twitter.com/l7ZjHnPIAU
Tennis balls are supposed to bounce. So what happened to this ball during a match at the Australian Open? A very likely explanation is that the surface layer had a vapor bubble underneath, so the kinetic energy of the ball went into deforming the surface https://t.co/VWiV89G2Twpic.twitter.com/fqL6krHXfu
