Antireflection Coating A glass lens (nglass = 1 52) has an antirefiection coating of MgF2(n = 1 38). (a) For 545-nm light, what minimum thickness of MgF2 will cause the reflected rays Rz and R4 in Figure 28-50 to interfere destructively, assuming normal incidence? (b) Interference will also occur between the forward-moving rays R1 and R3 in Figure 28-50. What minimum thickness of MgF2 will cause these two rays to interfere constructively? Incident light.

- Estimate the diameter of the Moon. During a total solar eclipse, the Moon passes in front of the Sun so that during “totality” their apparent sizes match and the Moon blocks light from the Sun shining on the Earth. a) What do you predict the size of the Moon would be if you were to use a pinhole in an aluminum holder, meter stick, and white paper screen to project light from the full Moon through a pinhole onto a screen that is one meter away from the pinhole? b) Describe in detail how you would use this apparatus and your knowledge of pinhole phenomena to estimate the diameter of the Moon. Assume that the distance between the Earth and the Moon is 250,000 miles.arrow_forwardThe following data was collected for a friction experiment in which an object was observed moving at constant speed over a surface. Graph the Applied Force versus the Normal Force and determine the coefficient of friction. Is this value the coefficient of kinetic friction or the coefficient of static friction?

Measurements and Linear Regression 1.1 Introduction The objective of this lab assignment is to represent measurement data in graphical form in order to illustrate experimental data and uncertainty visually. It is often convenient to represent experimental data graphically, not only for reporting results but also to compute or measure several physical parameters. For example, consider two physical quantities represented by x and y that are linearly related according to the algebraic relationship, y=mx+b, (1.1) where m is the slope of the line and b is the y-intercept. In order to assess the linearity between y and x, it is convenient to plot these quantities in a y versus x graph, as shown in Figure 1.1. Datapoints Line of regression Figure 1.1: Best fit line example. Once the data points are plotted, it is necessary to draw a "best fit line" or "regression line" that describes the data. A best fit line is a straight line that is the best approximation of the given set of data, and…arrow_forward
