Ah okay, so is my approach correct? And the textbook also notes that if the speed of the first medium is greater than the speed of the second medium, there will also be a phase shift of pi.
Hmm.. I was doing some other research and I found some other equations for thin-film interference..
\huge \phi=\frac{4\pi n_b t \cos(\theta_i)}{\lambda}+\phi_{r2}-\phi_{r1}
Could I make the assumption that since the speed will be greater in air than in the glass that it will experience a pi...
Homework Statement
You are designing a thin transparent reflective coating for the front surface of a sheet of glass. The index of refraction of the glass is 1.52 and when it is in use, the coated glass has air on both sides. Because the coating is expensive, you want to use a layer that has...
Or perhaps since..
# of fringes = 2x+1, where x=m, then 2m+1
a). if m halves, then # of fringes = x+1
b). if m doubles, then # of fringes = 4x + 1
Or maybe I'm just overthinking it?
Homework Statement
A diffracting grating casts a pattern on a screen located a distance L from the grating. The central bright fringe falls directly in the center of the screen. For the highest-order bright fringe that hits the screen, m=x, and this fringe hits exactly on the screen edge. This...
Okay, so if I look at the joint above the voltage source.. there is a current entering from the bottom and current leaving on both the left and right sides. So
I1-I2-I3=0
At join 2 (to the right of the resistor of the top), there is current entering from the left, and leaving out the right and...
