Method: Joules.refractive_index_v2

Defined in:
lib/joules/waves.rb

.refractive_index_v2(critical_angle) ⇒ Float

Note:

There is one other method for calculating refractive index.

Calculates the refractive index of a substance given critical angle.

Examples:

Joules.refractive_index_v2(48.7535) #=> 1.3299993207924483

Parameters:

  • critical_angle (Int, Float) —

    critical_angle != 0; critical_angle is in degrees

Returns:

  • (Float)

Raises:

  • (ZeroDivisionError) —

    if critical_angle = 0
