Part (a) What is the ratio of the slit width to the wavelength of the incident light?Part (b) What is the wavelength of the incident light, in nanometers? (6%) Problem 17: In a single-slit diffraction experiment, a coherent light source illuminates a slit in a barrier, and the resulting pattern is projected on ascreen that is separated from the barrier by a distance which is very large as compared to the slit width and the wavelength of the light source. A student makessketches of the resulting patterns. While the center of each bright or dark band is accurately represented, the shading is qualitative, and the choice of color maynot reflect the wavelength of the light source. The distance from the barrier to the screen is 3.5 m, and the slit has width 8.8 μm.-50.0 -40.0 -30.0 -20.0 -10.00.0 10.0 20.0 30.0 40.0 50.0y (cm)

In a diffraction experiment the 1st order light (m = 1) from a diffraction grating is falling onto a single slit (see picture below). The light from the slit is then observed on a second screen and the measured width of the central diffraction peak is found to be 8 mm. Calculate the number of lines per millimetres of the grating. The distance from the slit to the second screen is 1.37 m, the distance from the diffraction grating to the screen with the slit is 5 m, the slit width is 0.25 mm and the distance from the middle of the screen with the slit to the slit is 10 mm..
The phenomenon of diffraction occurs due to the tendency of waves to spread when they encounter an opening or obstacle. Single-slit diffraction is a phenomenon observed when a wave passes through a narrow opening, such as a slit, and spreads out after passing through it. The degree of diffraction depends on the dimensions of the aperture in relation to the wavelength of the incident wave. Statement: A slit of width a is illuminated with white light. For what value of slit width will we have the first minimum for blue light, with ? = 450 ??, appearing at ? = 25th? Question options: a) 1.50 µm b) 1.98µm c) 1.05µm d) 3.60 µm e) 0.37µm
(a) If the third-order maximum for monochromatic light falling on a double slit is at an angle of 20.7o at what angle (in degrees) is the fourth-order maximum? (b) What is the angle (in degrees) of the fourth minimum? (c) What is the highest-order maximum possible here?
A uniform plane wave is generated from a ham radio antenna on earth. The take off angle is 60 degrees (the angle ffrom ground going up is 60 deg). Using simple trigonometry the angle if incidence with the ionosphere would be 30 degrees. Assume the F layer of the ionosphere is 300 km above the earth. The wave frequency from the transmitter is 21 MHz. WIll this wave refract off the ionosphere and end up somewhere on earth? If yes, what is the distance it travels?
Monochromatic light is incident on a pair of slits that are separated by 0.210 mm. The screen is 2.60 m away from the slits. (Assume the small-angle approximation is valid here.)
