- A severely myopic patient has a far point of 5.00 cm. By how many diopters should the power of his eye be reduced in laser vision correction to obtain normal distant vision for him?On the Moon’s surface, lunar astronauts placed a comet reflector, off which a laser beam Is periodically reflected. The distance to the Moon is calculated from the round-trip time. What percent correction Is needed to account for the delay in time due to the slowing of light in Earth’s atmosphere? Assume the distance to the Moon is precisely 3.84108 m and Earth’s atmosphere (which varies in density with altitude) is equivalent to a layer 30.0 km thick with a constant index of refraction n= l.000293.Figure 25.54 shows a ray of light passing from one medium into a second and then a third. Show that 3 is the same as it would be if the second medium were not present (provided total internal reflection does not occur). Figure 25.54 A ray of light passes from one medium to a third by traveling through a second. The final direction is the same as if the second medium were not present, but the ray is displaced by x (Shawn exaggerated).
- Quasars, or quasi-stellar radio sources, are astronomical objects discovered in 1960. They are distant but strong emitters of radio waves with angular size so small, they were originally unresolved, the same as stars. The quasar 3C405 is actually two discrete radio sources that subtend an angle of 82 arcsec. If this object is studied using radio emissions at a frequency of 410 MHz, what is the minimum diameter of a radio telescope that can resolve the two sources?9:04 A A P all all 86 ... 1.02 mm-2 .05mm Турe ST 1.02 mm-4.1 1mm 9.
