Q
what is the equation for index of refraction + meaning for variables with speed
A
n=c/v c is the speed of light, v is the speed in a substance, n= index of refraction
2
Q
what is the second equation for the index of refraction + meaning of variables
A
n= sin01/sin0r 01= angle of incindence 02= angle of refraction
