Thank you for a quick respond. Would you please further explain how do you get the optical power formula? The only formula that I understand for optical power would be using Poynting vector (P = E*H = E^2/n), and I couldn't figure out how you get the term exp(-wbx/c). Also, b is the imaginary part of index of refraction and should be unitless. Here, 1/rad is still remained in n". The follow up question is why the accumulated phase per unit length should be equal to k or k=nk0? How the wavevector equal to the phase per unit length? Thank you.

- Case 1: Object distance d0= infinity. The figure below shows light rays coming from an object located at infinity, in front of a convex lens. Extend the 9 incident rays to the lens, and draw the transmitted rays in the correct direction. Use the figure, DO NOT substitute it with any other figure. Use the line to trace the 9 rays. Don't forget to place the arrow on each transmitted beam. Label each ray with its corresponding name: parallel ray, central ray, and focal ray. Image characteristics for Case 1: Object distance d0= infinity. Select those that apply: a) Reduced b) Real c) Erect d) Inverted e) Equal size f) Increased g) Virtual h) No image is formedA beam of light traveling through air is incident up a transparent material with refractive index 1.52 at an angle of 0;=28.34 as shown in the image below. What is the angle of the transmitted ray (0t) as measured with respect to the direction normal to the surface of the material (dashed line in the image below). Normal Reflected Incident ray ray Transmitted ray Note: It is understood that the unit of your answer is in degrees, however do not explicitly include units in your answer. Enter only a number. If you do enter a unit, your answer will be counted wrong.The figure below shows a monochromatic beam of light striking the right-hand face of a right-angle prism at normal incidence.

(Assume n3 = 1.0) Express your answer in degrees, to at least one digit after the decimal point.The figure below shows a light ray traveling in a slab of sodium chloride surrounded by air. The ray is incident on the right surface at an angle of 55° with the normal and then reflects from points A, B, and C. (Select all that apply.) A ray travels within a rectangular slab that is surrounded by air. The ray starts at the top of the slab and is incident on the right side of the slab at point A, and makes an angle of 55° to the normal. The ray reflects internally down and to the left and is incident on the bottom of the slab at point B, whereupon it reflects internally up and to the left until it is incident on the left side of the slab at point C, where it again reflects internally, up and to the right. (a) At which of these points does part of the ray enter the air? (Select all that apply.)
