How do you determine the angle of sunlight?

Answer 1

Mila Bautista

At noon, this angle is given by
#arc tan# (length of your horizontal shadow)/(your vertical height)

The angle at which light rays incident is used to define the sunshine angle.

This angle, measured from the Sun, is the angle 'a' formed by the direction of the sun.

with the vertical. a = 0 occurs when light strikes directly from overhead.

Every day, at sunrise and sunset, sunlight falls in a horizontal direction.

this angle is #90^o#.

This angle at noon, which is the precise moment between sunrise and sunset,

is minimum, therefore the length of your shadow is also

least.

If you measure the shadow's length at noon as L in relation to your

height H,

#tan a = L/H#, and so,#

#a = arc tan (L/H)#

Of course, this varies between #latitude+- 23.4^o#, in a year

The angle of sunlight can be determined using a solar angle calculator or by measuring the angle between the sunlight and a line perpendicular to the Earth's surface at a specific location and time.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
