Chapter 32, Problem 1Q

What would be the appearance of the Moon if it had (a) a rough surface; (b) a polished mirrorlike surface?

(a)

Expert Solution
Check Mark
To determine

The appearance of the moon if it had rough surface.

Answer to Problem 1Q

The appearance of the moon will be same as it looks now, because it had rough surface now also.

Explanation of Solution

If the moon had rough surface it will absorb light at some points and it will reflect light from some points, if the surface of the moon is completely rough and if it does not reflect any light then, it will not be visible to people on Earth.

During sometimes in the month, lit side of the portions of moon is visible and this happens because all parts of moon is reflecting back sunlight.

There are many such spots in the moon and every spot is a point source of light, which send reflections back to Earth from any part that is lit by sunlight.

Conclusion:

Thus, the appearance of the moon will be same as it looks now, because it had rough surface now also.

(b)

Expert Solution
Check Mark
To determine

The appearance of the moon if it had a polished mirror like surface .

Answer to Problem 1Q

If the moon had polished mirror like surface then it would be invisible to us.

Explanation of Solution

If the moon had polished mirror like surface then it would be invisible to us and only one small spot is visible that will be an image of a sun reflected by moon as it will behave like a mirror.

Some tiny small spots are also visible that would be the light from the stars reflected from the surface of the moon.

Even the portion of Earth which has light is also visible as one tiny spot.

The moon will behave like a mirror and it will reflect the light from everywhere which is reaching the moon and that light is visible on the surface as tiny spots.

Conclusion:

Thus, if the moon had polished mirror like surface then it would be invisible to us.

Suppose you are standing about 3 m in front of a mirror.You can see yourself just from the top of your head to yourwaist, where the bottom of the mirror cuts off the rest ofyour image. If you walk one step closer to the mirror(a) you will not be able to see any more of your image.(b) you will be able to see more of your image, belowyour waist.(c) you will see less of your image, with the cutoff risingto be above your waist.
The diameter of a penny is 19 mm. As we’ve seen, the moon subtends an angle of approximately 0.5° in the sky. How far from your eye must a penny be held so that it has the same apparent size as the moon?
The writing on the passenger-side mirror of your car says "Warning! Objects in mirror are closer than they appear" (Figure 1). There is no such warning on the driver's mirror. Consider a typical convex passenger-side mirror with a focal length of -80 cm. A 1.7-m-tall cyclist on a bicycle is 24 m from the mirror. You are 1.4 m from the mirror, and suppose, for simplicity, that the mirror, you, and the cyclist all lie along a line. Part A How far are you from the image of the cyclist? Express your answer with the appropriate units. L = 2.2 m Submit Previous Answers Correct Part B How far would you have been from the image if the mirror were flat? Express your answer with the appropriate units. Lf = 25 m Submit Previous Answers Correct Part C Figure What would the image height have been if the mirror were flat? What is the image height?
