The critical angle between two materials is 43o. If the angle of incidence is twice the angle of refraction, what are the angles of incidence and refraction?
Answer to relevant QuestionsThe critical angle for a glass– air interface is 41.11° for red light and 41.04° for blue light. (a) During the time the blue light travels 1.000 m, the red light will travel (1) more than, (2) less than, (3) exactly ...Two plane mirrors, M1 and M2, are placed together as illustrated in Fig. 22.25. (a) If the angle α between the mirrors 70o is and the angle of incidence, θi1 of a light ray incident on M1 is 35o, what is the angle of ...How can the focal length be quickly determined experimentally for a concave mirror? Can you do the same thing for a convex mirror? An object 3.0 cm tall is placed 20 cm from the front of a concave mirror with a radius of curvature of 30 cm. Where is the image formed, and how tall is it? Using the spherical mirror equation and the magnification factor, show that for a convex mirror, the image of an object is always virtual, upright, and reduced.
