Slide1
In the diagram at left, an observer in New York State “sees” the sun at three different noon-times during the course of a year (X, Y, and Z).
Which will create the longest shadow?

Angle of Insolation and Heat Energy
Textbook pg. 375Slide6
Which light waves are more concentrated?
Which light waves are more diffuse?Slide7
Which has more energy?
They are both equal!
One is more diffuse and one more concentrated!Slide8
Which diagram best shows the noon Sun providing an observer with the greatest amount of insolation?
WHY?Slide9
angle of insolation
energy from the sun!
So, why does it change?Slide10
Angles of insolation vary for 3 reasons: The season
(Angle of insolation is greater in summer)Slide11

Angles of insolation vary for 3 reasons: The season
(Angle of insolation is greater in summer)The latitude of the light
(closer to the equator = greater angle)Slide15Slide16
