As a single crystal is rotated in an x-ray spectrometer (Fig. 3.22a), many parallel planes of atoms besides AA and BB produce strong diffracted beams. Two such planes are shown in Figure P3.38. (a) Determine geometrically the interplanar spacings d1 and d2 in terms of d0. (b) Find the angles (with respect to the surface plane AA) of the n = 1, 2, and 3 intensity maxima from planes with spacing d1. Let = 0.626 and d0 = 4.00 . Note that a given crystal structure (for example, cubic) has interplanar spacings with characteristic ratios, which produce characteristic diffraction patterns. In this way, measurement of the angular position of diffracted x-rays may be used to infer the crystal structure. Figure P3.38 Atomic planes in a cubic lattice.

A light ray of wavelength 461.9 nm emerges from a 2-mm circular aperture of a krypton ion laser. Due to diffraction, the beam expands as it moves out. How large is the central bright spot at (a) 1 m, (b) 1 km, (c) 1000 km, and (d) at the surface of the moon at a distance of 400,000 km from Earth.
The diameter of the Arecibo radio telescope is 307 m. It can image radio source that emit electromagnetic waves with wavelength between 3 cm and 1 m. The Virgo Cluster is a cluster of galaxies whose center is ~53.8 Mly away from us. Assume the telescope is imaging at a wavelength of 63.3 cm and can just resolve two point sources of radio waves in the Virgo cluster. How close together could these point sources be, i.e. what is the minim distance between them in ly? Enter an integer.
Please answer both:The brightest star in the Pointers is α Centauri. It is actually a binary star, with two components known as α Cen A and α Cen B. They orbit each other for a period of about 80 years. At the moment they are separated by about 5 arcseconds in the sky. a) The average eye has a pupil diameter of 3mm, increasing to about 7mm at night. What is the theoretical best resolution for the human eye, at 500 nm? (Enter your answer in arc seconds, to the nearest whole number) b) Could you separate the two components with your naked eye (at 500 nm)?

One important goal of astronomers is to have a telescope inspace that can resolve planets like the earth orbiting other stars. If aplanet orbits its star at a distance of 1.5 * 10^11 m (the radius of theearth’s orbit around the sun) and the telescope has a mirror of diameter8.0 m, how far from the telescope could the star and its planet be if thewavelength used was (a) 690 nm and (b) 1400 nm? Use the Rayleighcriterion and give your answers in light-years (1 ly = 9.46 * 1015 m).
What angular resolution would you expect from a pinhole with a 0.55 mm diameter?(Assume light with a wavelength of 540 nm .) Express your answer using two significant figures. να ΑΣφ ? 0min rad
A new optical imaging satellite is being designed for the Maritime Domain Awareness mission. The satellite will be placed in a circular orbit at 5000 km altitude and be able to look off of nadir, giving a maximum range to the target of 7000 km. The desired resolution is 3 meters. What is the satellite's speed? Express answer in km/s to two significant digits.
in the question: A spy satellite orbiting 600 km above Earth is supposedly capable of counting individual people in a crowd in visual- wavelength images. Assume that the middle of the visual wavelength band is at 550 nm . Assume an average person has a size of 0.8 m as seen from above. Estimate the minimum telescope diameter that the satellite must carry. The previous expert used 1,22 instead of 2.06 to convert to angular distance. I thinkn he has to use the small-angular formula.
The 300 m diameter Arecibo radio telescope is observing the Andromeda galaxy at a wavelength of 14 cm. Part (a) What is the angle between two just-resolvable stars for this telescope in radians? Part (b) How close together could these point sources be at the 2.5 million light year distance of the Andromeda galaxy in ly?
