4:58 4 LTE Object POST-LAB Questions and Image Distance - Thin Lenses NAME JAIME 1. The function of lenses is based on the law of refraction A light beam is traveling from the medium 1 where its speed is V., to the medium 2 where its speed is V2 = 0.8 V, a) If the first medium is the air (n = 1), what is the index of refraction for the second medium? b) If the angle of incidence is...
(a) Briefly explain what is meant by the following terms: refraction, refractive index, angle of incidence, angle of refraction. [4 marks] (b) The drawing shows four different situations in which a light ray is traveling from one medium into another. In some of the cases, the refraction is not shown correctly. For cases (i), (ii), and (iii), the angle of incidence is 55°; for case (iv), the angle of incidence is 0°. Identify which cases are incorrectly drawn and determine...
Partner: Date Name 11 Snell's Law Introduction When light passes from one material to another it is always bent away from its original path. This process is known as refraction and the change in direction depends on the change in optical density (or refractive index) of the two materials. A larger change in refractive index results in a larger change in angle between incoming and outgoing light beams. A light beam bends closer to the normal in the material with...
