- The most common type at mirage is an illusion that light from faraway objects is reflected by a pool of water that is not really there. Mirages are generally observed in deserts when there is a hot layer of air near the ground. Given that the reflective index of air is lower for air at higher temperatures, explain how mirages can be formed.arrow_forwardWhy is the index of refraction always greater than or equal to 1?arrow_forwardUsing Snell’s law, explain why total internal reflection occurs. Hint: using the example of a glass-to-air interface, use Snell’s law to predict the angle of refraction for angles of incidence less than, equal to, and greater than the critical angle.arrow_forward
- In three arrangements you view two closely spaced small objects that are the same large distance from you. The angles that the objects occupy in your field of view and their distances from you are the following: (1) 2f and R; (2) 2f and 2R; (3) f/2 and R/2. (a) Rank the arrangements according to the separation between the objects, greatest first. If you can just barely resolve the two objects in arrangement 2, can you resolve them in (b) arrangement 1 and (c) arrangement 3?arrow_forward(no solution needed)A light ray from air is incident to the surface of water ( n=1.33) at an angle of 30°.

- This phenomenon is called Total Internal Reflection (TIR). What do you think would be some practical purposes of TIR in modern technology? Please name at least one example and explain your answer in at least two complete sentences.arrow_forward8. What is the angle of deviation if a ray of light in water is incident at an angle of 50 degrees and the angle of refraction is 35 degrees? Draw & compute.arrow_forwardQuestion: A fish is swimming 2m below the surface of a calm lake. At what angle to the horizontal must the fish look to observe a fisherman sitting ~ 50 m away at the edge of a lake ( the refractive index n= 1.33 for water). Solution: In this case the way the fish can see horizontally across the lake is when the angle of incidence is nearly 90 degrees in the air. This corresponds to the light ray inside the water being refracted close to the critical angle for total internal reflection where sin θc = 1/n, giving θ = 48.6 degrees. This is with respect to the normal, so the horizontal angle the fish needs to be looking at is 41.4 degrees. Here, I understand the critical angle is 48.6 degree. However, what does it mean by "This is with respect to the normal, so the horizontal angle the fish needs to be looking at is 41.4 degrees." ?arrow_forward
- Chapter 25: Problem 6: Suppose you have an unknown clear substance immersed in water, and you wish to identify it by finding its index of refraction. You arrange to have a beam of light enter it at an angle of 45.0⁰ with respect to the normal, and you observe the angle of refraction to be 40.3⁰. For convenience, the index of refraction for a variety of materials is provided below. a) What is the index of refraction of the substance? b) What is its likely identity?arrow_forwardA ray of light passed from air to a medium making an angle of incidence60 0 and angle of refraction 45 0 . 3(i) State if the refractive medium is denser or lighter than air.(iii) Also, explain- why does light bend after refraction in the refractive medium?arrow_forwardDoes refraction make a swimming pool seem deeper or shallower?
