In a double slit experiment, the ratio of slit separaton to the slit width is 2.2 (five bright fringes in the central peak). If the slit separation is increased by a factor of three, keeping the slit width the same, how many fringes will now fit in the central peak? 15 3 13 10

In a double slit experiment, the ratio of slit separation to the slit width is 1.7 (three bright fringes in the central peak). If the slit separation is increased by a factor of four, keeping the slit width the same, how many interference fringes will now fit in the central diffraction peak? 6 13 5 12

In a double-slit diffraction experiment, two slits of width 13.8 × 10-6 m are separated by a distance of 25.4 × 10-6 m, and the wavelength of the incident light is 692 nm. The diffraction pattern is viewed on a screen 5.32 m from the slits. Assume IP is the intensity at a point P, a distance y = 80.1 cm on the screen from the central maximum. Find the ratio of the intensity at P and the intensity at the center of the diffraction pattern (I0), IP/I0.

In a particular application, an n-channel MOSFET operates with VSB in the range 0 V to 4 V. If Vt0 is nominally 1.0 V, find the range of Vt that results if γ = 0.5 V1/2 and 2φf = 0.6 V. If the gate oxide thickness is increased by a factor of 4, what does the threshold voltage become?
