Derek Pan Physics 6CL Lab 1 1. No 2. The angle is more extreme when refracted 3. At about 45 degrees, the beam becomes reflected 4. No 5. 1*sin(70)=nplastic*sin(40) n(1)=1.46 1*sin(45)=nplastic*sin(30) n(2)=1.41 [n(1)+n(2)+n(3)+n(4)]/4=avg index of refraction of plastic n plastic=1.45 6. 1.45=(299793468m/s) / (V of plastic) V plastic = 106754115 2.1 The rainbow is most visible at 85 degrees. This is probably because it is just before 90 degrees (angle with no refraction or reflection) 2.3 The beam on the opposite side is parallel to the first beam, but it is slightly lower. It is lower because when the light first hits the plastic at a slanted angle, the velocity drops and it changes directions (downwards). Then, when the light leave is plastic on the opposite side, it resumes its faster velocity and angles back upwards to be parallel.

Unformatted text preview: 2.4 No 2.5 Purple: 1.47*sin(x)=1*sin(17) Degrees of refraction =11.47 degrees Green: Degrees of refraction = 11.54 degrees Orange: Degrees of refraction = 11.57 degrees 2.6 In diamonds, there is a large difference (about 1.4) of the index of refraction when compared to a vacuum (1). This is what causes the rainbow. 4.1 There are more reflections. 4.2 They originate from the starting image. 4.3 There are 4 images at 90 degrees. 4.4 It comes from a reflection of the mirror itself. 5.1 The image is upside down and is magnified at about 0.1 times the original. 5.2 The image is still upside down. It gets smaller and smaller as well as moving upwards until it is almost impossible to make out. 5.3 It is magnified smaller and smaller. 6.1 The focal length is about 5.2 cm...
