A pure red object on a black background seems to disappear when illuminated with pure green light. Explain why.
Go outside on a clear night, wait 15 minutes for your eyes to adjust to the dark, and look carefully at the brightest stars. Some should look slightly red and others slightly blue. The primary factor that determines the color of a star is its temperature. Which is hotter: a blue star or a red one? Explain
(a) What is me ratio of the speed of red light to violet light in diamond, based on Table 25.2? (b) What is this ratio in polystyrene? (c) Which is more dispersive?
Suppose a star 1000 times brighter than our Sun (that is, emitting 1000 times the power) suddenly goes supernova. Using data from Table 7.3: (a) By what factor does its power output increase? (b) How many times brighter than our entire Milky Way galaxy is the supernova? (c) Based on your answers, discuss whether it should be possible to observe supernovas in distant galaxies. Note that there are on the order of 1011 observable galaxies, the average brightness of which is somewhat less than our own galaxy.
Why are light-years more convenient than miles, kilometres, or astronomical units for measuring certain distances?
Would the critical angle for a glass—water interface be less than, equal to, or greater than the critical angle for a glass—air interface? Siw?
Determine whether each of the following statements is true (T) or false (F). (a) The angle in Snell's law is measured between the ray and a line perpendicular to the surface. (b) The speed of light in a material increases as the materials index of refraction increases. (c) The ratio v/ of a photons speed to its wavelength has the same value for any index of refraction n. (d) Photons of blue light have a higher energy than photons of red light. (e) A photons energy depends on its brightness.
A farmer wants to fence off his four-sided plot of flat land. He measures the first three sides, shown as A, B, and C in Figure 3.62, and then correctly calculates the length and orientation of the fourth side D. What is his result?
An idealized radiating object does not reflect or scatter any radiation but instead absorbs all of the electromagnetic energy that falls on it. Can you explain why astronomers call such an object a blackbody? Keep in mind that even stars, which shine brightly in a variety of colors, are considered blackbodies. Explain why.
Narrow, parallel, glowing gas-filled tubes in a variety of colors form block letters to spell out the name of a nightclub. Adjacent tubes are all 2.80 cm apart. The tubes forming one letter are filled with neon and radiate predominantly red light with a wavelength of 640 nm. For another letter, the tubes emit predominantly blue light at 440 nm. The pupil of a dark-adapted viewers eye is 5.20 mm in diameter. (a) Which color is easier to resolve? State how you decide. (b) If she is in a certain range of distances away, the viewer can resolve the separate tubes of one color but not the other. The viewers distance must be in what range for her to resolve the tubes of only one of these two colors?
Explain why we have to observe stars and other astronomical objects from above Earth’s atmosphere in order to fully learn about their properties.
The speed of the Earth in its orbit is 29.8 km/s. If that is the magnitude of the velocity v of the ether wind in Figure P39.3, find the angle between the velocity of light c in vacuum and the resultant velocity of light if there were an ether.
