For measurement of potential difference, potentiometer is preferred in comparison to voltmeter because :

Potentiometer is more sensitive than voltmeter
The resistance of potentiometer is less than voltmeter

Question 1

In a double-slit experiment, the 4th-order maximum for light of wavelength 450 nm is located 20 mm from the central maximum on a screen 1.5 m away from the slits. Light of wavelength 600 nm is then projected through the same slits. How far from the central bright spot will the 2nd-order maximum of this light be located? [10 Pts.] P oriented vertically, P at 90Â° with respect to the vertical, and P at 90Â° to the vertical. Unpolarized light of intensity Io is incident on the first polarizer from the left. The final intensity of the light after passing through the three polarizers is 0.08Io. Determine the angle. [10 Pts.]

Question 2

The average person thinks of laser beams as pencil-thin rays of light, but let's calculate what actually happens to a laser beam as it propagates a large distance away. Let a plane wave be incident on a wall with a hole in it. To turn the plane wave into a laser beam, let's make the hole a "Gaussian hole" which has a transmission, t(x) = exp[-1/2(x/w^2)], and to simplify the problem, just consider the x-direction (the answer is the same in the y-direction if the hole is Gaussian in that direction also).

Compute the shape of the beam intensity, I(x), a large distance away (by shape, I mean just the functional form, so you can neglect any factors that don't depend on x and need only use the proportional to (â‰ˆ) symbol, rather than equals (=) when calculating the electric field).
If we call w in the above formula the spot size of the beam at the wall, use the same definition of spot size to determine the size of the beam (call it w') a distance away as a function of x, w, and A (the wavelength of the beam). In other words, set the resulting exponential of the intensity far away equal to exp[-(x'/w)^2] and solve for w'.
As long as the Fraunhofer approximation is valid, is the beam far away larger or smaller than that nearby?
Finally, which yields a smaller spot far away, a small or large spot nearby?
