Organ Pipe

This activity invites students to make a model organ pipe and explore how to amplify a tuning fork by holding it over the pipe and changing the length of the pipe. They investigate how at certain pipe lengths, the pitch made by the tuning fork sounds very loud as it resonates with the air column in the pipe. The activity ...

The physics of invisibility cloaks

Could an invisibility cloak actually work? Prashanth and Maria from MIT explore this idea and demonstrate the cool ways that light bounces, bends and mixes. How do the wings of the Morpho Butterfly give clues about how an invisibility cloak could work? How would light need to be channelled in order for something to seem invisible?
