Attention: alien alert! 👽 Who noticed it?!

[1] Next, we’ll show the spectra of different lights. In front, we have LED lamps, in the middle – energy-saving lamps, and in the back, old incandescent bulbs.
The spectra – you probably remember from school: when sunlight passes through a prism, you get a rainbow. Here, we have diffraction gratings, and I’ll demonstrate this now.

[2] I’m holding the diffraction filter in front of my smartphone camera, and you can see this funny little rainbow.

[3] On the left, you see colors from an energy-saving lamp – rarely used nowadays – and next to it, the old incandescent bulbs. The energy-saving lamps show only five colors, while the incandescent bulbs display the full spectrum.
