Twisting Light

Twisting light might sound like a funny idea. But, if engineers had not found a way to twist light in a controlled way then the displays in your mobile phone, laptop and maybe even your TV would all remain black. In this masterclass you will actually twist light. You will see how this can produce surprising effects and beautiful colours. Moreover, you will learn how giving light a twist is used to build displays and to control the quality of food and pharmaceutical products. In this module, students learn how to rotate the polarisation of linearly polarised light and how polarisers work. Students will also experiment with the effect of polarized light in everyday devices such as smart phones and sunglasses. They also learn how to build their own polarimeter and measure the rotation of polarisation due to a sugar solution.
