< < Lecture 30 Lecture 32 > > Video Transcript Hello there! Welcome to lecture 31: light quanta! At this point, we’ve learned an awful lot about light. We’ve seen how it’s emitted, and we’ve seen how it travels through space and different media. Hopefully you’re convinced that light exhibits Read more…
< < Lecture 29 Lecture 31 > > Video Transcript Hello there! Welcome to lecture 30: light emission! From the lights we use in our homes, to the lights illuminating our smart phone screens, to the sun in the sky, light emission is a very big part of our lives. Read more…
< < Lecture 28 Lecture 30 > > PhET Wave Interference Simulation Play around with different types of waves to learn about interference and diffraction. Video Transcript Hello there!
