How does the altitude of the Sun at noon on the same day in the Northern Hemisphere’s summer compare for two observers at lati-
Zepler [3.9K]

Answer:

It is 42° higher for the observer at 12° north because of the differ- ence in latitude.

Explanation:

The sun's altitude can be given by the following formula:

S = 90 - L + D

In which S is the sun's altitude, L is the latitude of the place and D is the declination of the sun.

Since the comparasion occurs at the same day, the value of D will be the same for both cases, so it can be disconsidered in our calculation.

First observer

L = 12

S = 90 - L + D = 90 - L = 90 - 12 = 78

Second observer:

L = 54

S = 90 - L + D = 90 - L = 90 - 54 = 36

The correct answer is:

It is 42° higher for the observer at 12° north because of the differ- ence in latitude.
