Science KS2: The work of the ‘father of optics’ Alhazen

In this vlog style film, Alhazen talks about being a physicist and mathematician, with a specialism in optics and light.

He explains that we see because light bounces off objects into our eyes. He outlines the need for observations and making a hypothesis, not just using abstract reasoning.

He goes on to explain his theory that light travels in straight line, and how he proved this by carrying out an experiment with two lanterns.
