Speaker: Arnab Bhattacharya (HBCSE)
As we prepare for Holi, the festival of colour, let’s ask ourselves what is colour after all? We live in a world bathed in light, and at least most of us can see the various colours of objects that make our world so beautiful. But what is colour anyway? Is there pink in a rainbow? Why do two people see the same colour differently? Well, colour is all in our head! While light has intrinsic physical properties such as wavelength and intensity, colour is not actually a property of light or of objects that reflect light but entirely a sensation that arises in our brain, due to a complex chain of events starting from when light enters the eye. And the brain can even be fooled to see colours that don’t exist! Join us in our Holi special as we dive into the world of colour!
