Light traveling through an optical fiber (index of refraction = 1.44) reaches the end of the fiber and exits into air. If the angle of incidence on the end of the fiber is 50°, what is the angle of refraction outside the fiber? [Round to the nearest tenth.]

What are similarities and differences of reflection, refraction, diffraction and absorption?

An ideal polarizer with its transmission axis rotated 30 degrees to the vertical is placed in a beam of unpolarized light of intensity 10w/m^2. after passing through the polarizer, what is the intensity of the beam? a. 8.7 w/m^2 b. 7.5 w/m^2 c. 5.0 w/m^2 d. 10 w/m^2 e. 2.5 w/m^2
