Colourful Weather, Ep 3: Why sunsets and sunrises will never be blue or green

Can you guess how many sunsets and sunrises an astronaut on the International Space Station sees every 24 hours? Sixteen! Imagine seeing all those spectacular colours so many times a day (even if the view lasts only a few seconds as they zoom by).

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?

Bending light

This is an interactive resource about refraction. Students explore bending of light between two media with different indices of refraction. They can see how changing from air to water to glass changes the bending angle and experiment with prisms of different shapes and make rainbows. This interactive resource is supported ...
