The effect of error in a measured angle decreases with increasing length of sight distance True False

Riley, a student, notices that the protractor tool does not measure the angle just as the ball leaves the surface. She sees that the ball must travel some distance before it crosses the protractor, so the direction of travel may have changed as the ball moves upwards. She says that this is the cause of the discrepancy between her predicted angle and the measured angle.Does this reasoning explain the discrepancy between your predicted angle and your measured angle?

Through the equation n1 sin θ1 = n2 sin θ2, the Snell’slaw relates the incident angle θ1 of a ray traveling in amedium of index n1 to the refraction angle θ2 of the samelight ray in the medium of refraction index n2. Find n2 andits uncertainty from the following measurementsθ1 = 22.0◦ ± 0.2◦θ2 = 16.3◦ ± 0.2◦n1 = 1.000 (assumed to be exact)Note that δθ must be converted into radians when youcompute the uncertainty. In calculus, we only use radiansin trigonometrical functions
