hello. we have our experiment. this is the isntruction HELP ME  At the middle of a paper protractor, set a crown glass plate. Shine a laser pointer on the side of the glass plate.  After that, identify the normal to the incident ray. Then, measure the angle of refraction of each of the following angles of incidence: 10°, 15°, 20°, 25°, 30°, 35°. On a graph, plot the sine of the angle of incidence (x-axis) versus the sine of the angle of refraction (y-axis). Using this graph, identify the refractive index of glass and compute the percentage error of the index of refraction. we still haven't done the experiment but my teacher is asking me: WHAT IS THE BEST STATISTICAL TOOL FOR THE EXPERIMENT?   I do not know if it is t-test z-test etc.    thanks

Calculate the angle of refraction at the air/core interface, r . critical angle, c and incident angle at the core/cladding interface, i . Will this light ray propagate down the fiber? You have the following data: nair = 1, ncore = 1.46, ncladding =1.43, incident =12o r = 8.2o, c = 78.4o, i = 81.8olight will propagate Formula summery Index of Refraction n= n sin 01= n, sin 0, o = sin1(2) Snell's Law Critical Angle Acceptance angle a= sin1 Numerical Aperture NA = sin a = ni- nị

A paperweight is made of a solid glass hemisphere of index of refraction 1.54. The radius of the circular cross section is 4.45 cm. The hemisphere is placed on its flat surface, with the center directly over a 1.90 mm long line drawn on a sheet of раper. a. What is the image distance (with the correct sign)? cm b. What is the magnification of the image? c. What length of line is seen by someone looking vertically down on the hemisphere? mm

Using the figure below, find the angles of refraction for a light ray passing from air into glass with the following angles of incidence: 5°, 10°, and 20°. 45 40 35 30 25 20 15 10 10 20 30 40 50 60 70 80 90 Angle in air (*) O10° %3D 020° Do you notice a trend in the resulting values? If so, describe it. O Doubling the angle of incidence approximately halves the angle of refraction. O Doubling the angle of incidence approximately doubles the angle of refraction. O Doubling the angle of incidence approximately quadruples the angle of refraction. There is no trend in the resulting values. Based on your observations, what would you predict the angle of refraction to be for an angle of incidence of 40°? How does your value compare with that inferred from the figure? () ssed u asuy
