Excellent video. You covered the topic very thoroughly. All I will add is you should give a warning for looking into the sun directly and for laser pointers as many exceed the eye safe rating.

This was FANTASTIC.

Just to clarify, this is a spectroscope as I am aware. A spectrometer analyzes the band of light!

Hi could this be circular dichroism spectrometers? Need reply asap

thank you for the tutorial. i saw some others where they get a tissue roll and they put the refraction grating on one end and the slit on the other. why do some others place the cd at 45 degrees? what is the difference

[@Berghiker]

Maybe from a laser pointer it's not good to look at. Have you tried it?

[@wonkiluvs]

can i use sunlight for the experiment?

I thought he is going to make a Circular Dichroism (CD) Spectrometer. But he actually made a Compact Disc (CD) Spectrometer LOL

These are not High Pressure Sodium street lights, they are LEDs
