A light ray with a wavelength of 589 nanometers (produced by a sodium lamp) traveling through air makes an angle of sin 0₁ V₁ incidence of 55 on a smooth, flat slab of dense flint glass. Use Snell's Law, where the index of refraction is 1.66. The angle of refraction is approximately degrees. (Type an integer or decimal rounded to two decimal places as needed.) -=, to find the angle of refraction sin 82 V2
