2. What is the intensity of this electrom tank containing methanol has walls 2.00 cm thick made of glass of refractive index 1.550. Light from the outside air strikes the glass at a 40 angle with the normal to the glass. a refractive index of Draw the path of the ray and identify angles of incident and refractive ray. Fing the angle the c) The tank is emptied and refilled with an unknown liquid. If light incident at the same angle as in part (b) enters the liquid in the tank at an angle of 20.2. from the normal, what is the refractive index of the unknown liquid?

1. Horizontally polarized light is incident on a polarizing filter with an axis of polarization that makes an angle of 32° with the vertical. a. What percentage of the incident light is blocked by the polarizer? b. What angle should the polarizer make with the vertical to block exactly half of the incident light?

QUESTION 12 A tank containing methanol has walls 2.50 cm thick made of glass of refractive index 1.55. Light from the outside air strikes the glass at 42.30 with the normal to the glass.
