The mass of a solid hemisphere is measured once with a digital balance whose resolution is 1 g. The result is m = 50 g. With a caliper, the resolution of which is 0.05 mm, repeated measurements of the diameter D of the hemisphere are carried out. The values obtained for D: 100.30 mm; 100.00 mm; 100.60 mm; 100.10 mm; 100.25 mm; 100.50 mm; 100.40 mm; 100.20 mm; 100.30 mm; 100.35 mm. Knowing that the standard deviation of the set of diameter values is 0.18 mm, the result of measuring the diameter d is: (a) (1002.30 ± 0.05) mm (b) (100.300 ± 0.029) mm (c) (100.30 ± 0.18) mm (d)(100.300 ± 0.057) mm

The mass of a solid hemisphere is measured only once with a digital balance, whose resolution is 1 g. The result is m = 50 g. With a caliper, the resolution of which is 0.05 mm, repeated measurements of the diameter D of the hemisphere are carried out.

The resolution of a TEM is limited by diffraction (Rd) as discussed in Chapter 1, Eq. (1.3)), and by the spherical aberration which is expressed as: Rsph =Csα3, where Cs is the spherical aberration coefficient and α is the half-angle of the cone of light entering the objective lens. The TEM resolution is the quadratic sum of the diffraction resolution and spherical aberration resolution, given by the expression: R=√(R_d^2 + R_sph^2 ) The minimum R is obtained when Rd ≅ Rsph. Estimate the optimum value of α and resolution limit of TEM at 100–200 kV. (Cs ≅ 1 mm for an electromagnetic objective lens).
A horizontal laser beam of wavelength 632.8 nm has a circular cross section 2.00 nun in diameter. A rectangular aperture is to lie placed in the center of the beam so that when the light falls perpendicularly on a wall 4.50 m away, the central maximum fills a rectangle 110 mm wide and 6.00 mm high. The dimensions are measured between the minima bracketing the central maximum. Find the required (a) width and (b) height of the aperture. (c) Is the longer dimension of the central bright patch in the diffraction pattern horizontal or vertical? (d) Is the longer dimension of the aperture horizontal or vertical? (e) Explain the relationship between these two rectangles, using a diagram.
Both sides of a uniform film that has index of refraction n and thickness d are in contact with air. For normal incidence of light, an intensity minimum is observed in the reflected light at λ2 and an intensity maximum is observed at λ1, where λ1 > λ2.

In an experiment to monitor the Moon’s surface with a light beam, pulsed radiation from a ruby laser (wave = 0.69 mm) was directed to the Moon through a reflecting telescope with a mirror radius of 1.3 m. A reflector on the Moon behaved like a circular flat mirror with radius 10 cm, reflecting the light directly back toward the telescope on Earth.The reflected light was then detected after being brought to a focus by this telescope. Approximately what fraction of the original light energy was picked up by the detector? Assume that for each direction of travel all the energy is in the central diffraction peak.
