reflected image


I love this image of reflection. I'm going to put a camera onto this image and show it through a small screen aside.

Interference patterns from a diffraction grating


Interference patterns from a projector transmitting light through a diffraction slide, creating different orders of the visible spectrum. The demonstration was carried out by the Harris Academy physics department on the open evening on 20 November 2008.

diffraction grating


Spectrum of white light by a diffraction grating. With a prism, the red end of the spectrum is more compressed than the violet end.
