Problem 9: You shine a blue laser light-beam with wavelength of 445 nm from air to an unknown material at an angle of incidence of 35.0 You measure the speed of light in this unknown material has decreased to a value of 1.20 x 10 m/s. a) What is the index of refraction of this material? b) What is the angle of refraction inside this material? c) If this blue light-laser were to come from inside this material out to the air, find the critical angle at which the refracted ray emerges parallel along the boundary surface. d) What is the condition for this blue light laser to experience total internal reflection?
