Method: Joules.refractive_index_v1

Defined in:
lib/joules/waves.rb

.refractive_index_v1(angle_of_incidence, angle_of_refraction) ⇒ Float

Note:

There is one other method for calculating refractive index.

Calculates the refractive index of a substance given angle of incidence and angle of refraction.

Examples:

Joules.refractive_index_v1(50, 35) #=> 1.3355577296591308

Parameters:

  • angle_of_incidence (Int, Float) —

    angle_of_incidence is in degrees

  • angle_of_refraction (Int, Float) —

    angle_of_refraction != 0; angle_of_refraction is in degrees

Returns:

  • (Float)

Raises:

  • (ZeroDivisionError) —

    if angle_of_refraction = 0
