A beam of light is incident on a plane mirror at an angle relative to the surface of the mirror. (a) Will the angle between the reflected ray and the normal be (1) α, (2) 90o – α, or (3) 2α? (b) If α = 33o, what is ...A 45o – 90o – 45o prism (Fig. 22.27) is made of a material with an index of refraction of 1.85. Can the prism be used to deflect a beam of light by 90o. (a) In air? (b) What about in water? An outdoor circular fish pond has a diameter of 4.00 m and a uniform full depth of 1.50 m. A fish halfway down in the pond and 0.50 m from the near side can just see the full height of a 1.80-m-tall person. How far away from ...The angle of incidence and angle of refraction along a particular interface between two media are 30o and 40o, respectively. What is the critical angle for the same interface? 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 ...Post your question
