Fredy Jeanrenaud / EyeEm/Getty Images/EyeEmIt's another "Back To School" episode where we take a concept you were maybe taught in school as a kid, but didn't really learn or just forgot.
Short Wave producer Thomas Lu and host Maddie Sofia go on a journey to explore what a rainbow exactly is and how we see them...with some help from Kerstin Nordstrom, professor of physics at Mount Holyoke College.
