Explain how microscopes can use wave optics to improve contrast and why this is important.
The \(300 - m\)-diameter Arecibo radio telescope pictured in Figure \(27.28\) detects radio waves with a \(4.00{\rm{ }}cm\) average wavelength.
(a) What is the angle between two just-resolvable point sources for this telescope?
(b) How close together could these point sources be at the \({\rm{2}}\) million light year distance of the Andromeda galaxy?
Figure \(27.28\) A \(305 - m\)-diameter natural bowl at Arecibo in Puerto Rico is lined with reflective material, making it into a radio telescope. It is the largest curved focusing dish in the world. Although \(D\) for Arecibo is much larger than for the Hubble Telescope, it detects much longer wavelength radiation and its difdfraction limit is significantly poorer than Hubble's. Arecibo is still very useful, because important information is carried by radio waves that is not carried by visible light. (credit: Tatyana Temirbulatova, Flickr)
At what angle is the fourth-order maximum for the situation in Exercise 27.6? 13.
(a) What visible wavelength has its fourth-order maximum at an angle ofwhen projected on a 25,000 -line-per-centimeter diffraction grating? (b) What is unreasonable about this result? (c) Which assumptions are unreasonable or inconsistent?
If a diffraction grating produces a first-order maximum for the shortest wavelength of visible light at, at what angle will the first-order maximum be for the longest wavelength of visible light?
