Question

which of the following is Snell's law. a)n1 sin I =sin r/ n2. b)n1/n2=sin r/ sini. c)n2/n1,=don't/sin i. d) n2 sin I=constant​

Answer 1

Snell's Law states that the ratio of the sine of the angles of incidence and transmission is equal to the ratio of the refractive index of the materials at the interface.
