Question

Exercise #5 Apparent and Absolute Magnitude A) Ranking Instructions: Rank the distance (from greatest to least) that each car is from front of the image/observer: Greatest 1. _*.Least Or, the distance to each car is the same: (indicate with x or check mark) Explain your reasoning for your ranking: A B) Ranking Instructions: Rank the apparent brightness (from greatest to least) of each car's headlights to the observer in the foreground. Think of distant cars on the highway verses closer stars. Greatest 1. _*.Least Or, the apparent brightness of each car's headlights is the same (indicate with x or check mark) Explain your reasoning for your ranking: u C) Ranking Instructions: Rank the/true (intrinsic) brightness (from greatest to least) that each car's headlights: Greatest 1. 3 4. Leas Or, the actual brightness of each car's headlights is the same: (indicate with x or check mark) Explain your reasoning

Explanation / Answer

(A) Greatest distance from observer 1. B ,2. C , 3. D  4. A  

The distant object is appearing to be of small size.

(B) Apparent brightness in highest to lowest order, A - D - C - B

the apparent brightness is proportion to inverse square distance.

(C) True brightness

actual brightness is same for every car.

actual brightness is the brightness that is observed from a common distance from each car.
