I know chilled sodium slows light… does heat increase the speed of light?
not directly heat would have a direct affect on the wavelength of light. more heat=smaller wavelength(intensity of light would increase). smaller wavelength=larger velocity. So, yes heat increases speed of light but not directly. 74.125.113.132/search?q=cache:Pk3...
light cannot exceed lightspeed, but it can slow down according to modern understand of physics
