• Reflection and refraction are examined.

  The equation for the critical angle could be i_c = sin^-1(1/u) Reflection and refraction is examined for a multiple ray projector. The expert determines if it is possible to calculate the index of refraction of plastic from the critical angle.

• Physics: A light beam strikes a plate of crown glass at an angle of 30 degrees.

  Substituting values of angle i and μ we get: sin 30O/sin r = 1.52 => sin r = sin 30O/1.52 = 0.5/1.52 = 0.329 => Angle of refraction r = sin-10.329 = 19.2O Critical Angle

• Problems involving the refraction of light

  For a ray of light travelling from a denser to a rarer medium, there is an angle known as critical angle such that if the angle of incidence is greater than the critical angle, the ray suffers total internal reflection back into the denser medium.
