@wsuchemistry: The spooky chemistry show was interrupted by a visit from Darth Vader, but our Jedi chemistry professors won the day! Color is determined by the frequency of light, with the visible spectrum ranging from red (lowest frequency, to violet (highest frequency). Darth Vader lightsaber’s is red and weak compared to the Jedi’s lightsaber which blue and powered by a kyber crystal. And Yoda’s green lightsaber has a special connection to the Force. #wsuchemistry #lightsabers #darthvader #jedis #usetheforce #lukeiamyourfather #HappyHalloween #scienceshow #chemistryindetroit #maytheforcebewithyou #scienceismagic #waynestateuniversity @Tommy Technetium @Andrea Matti
