(a)
The minimum thickness of coating needed to cancel visible light of wavelength

Answer to Problem 100QAP
The intensity of polarized light that passes through the stack of polarizing sheets is
Explanation of Solution
Given:
Refractive index for coating =
Refractive index for solar cell panel =
Formula used:
Formula for destructive interference due to thin film,
Calculation:
Since, path of light wave on the top and bottom face of the film changes by
So, reflected waves would be in phase. So, path difference between top and bottom surface of the film would be as,
Conclusion:
Thus, the minimum thickness of coating that cancel visible light of wavelength
(b)
The wavelength of visible light that cancel and reinforce the reflected light when thickness is increases by three times to its initial value

Answer to Problem 100QAP
The wavelength of the reflected light that cancels in air is
Explanation of Solution
Given:
Thickness of coating =
Refractive index for coating =
Refractive index for solar cell panel =
Formula used:
Formula for destructive interference due to thin film,
Calculation:
For destructive interference,
As we increase m, wavelength would be less than 240nm.
So, there is only one reflected wavelength lies in visible region that cancels is
Now, for constructive interference,
Conclusion:
Thus, the wavelength of reflected light that cancels is

- A man holds a double-sided spherical mirror so that he is looking directly into its convex surface, 33 cm from his face. The magnification of the image of his face is +0.17. What will be the image distance when he reverses the mirror (looking into its concave surface), maintaining the same distance between the mirror and his face? Be sure to include the algebraic sign (+ or -) with your answer.arrow_forwardHow do you draw a diagram of the ruler and mass system in equilibrium identifying the anti-clockwise torque and clockwise torque? How do I calculate the anti-clockwise torque and the clockwise torque of the system with the ruler and the washers, does it come from the data in table 4?

- Did your experiment results in Data Table 3 verify, to within a reasonable experimental error, the condition of equilibrium of Equation 6: Στanti-clockwise = Στclockwise? Support your response with experimental data. What does this Σ mean? My results do not show they are equal to each other, what does this mean then, and what does the data show?
