Beam Latitude Angle of Beam ChordRelative intensity incidence width Length Beam width Chord length 100% cm cm 0 30° 60 90 1.0 1.0 Figure 2. Angle of incidence and relative insolation at 0, 30°, and 60 latitudes 1. For each latitude, draw a chord connecting where the upper part of the beam intersects the Earth's surface to where the lower part intersects the Earth's surface. For clarity, it is best if you can do this in a color other than black. Using a cm scale, measure the length of each chord. For example, the chord length of beam A should be 1.0 cm. Enter your measurements in the table above The acute angle between the beam and the Earth's surface is known as the angle of incidence 2. Using a protractor, measure the angle of incidence between the chord and the centerline of each beam. For example, at the Equator (Beam A, latitude 0'), the angle of incidence is 90 whereas at the poles (latitude 90"), the angle of incidence is 0. Enter your measurements in the table above The relative intensity is a measure of the amount of insolation that is available at a given latitude relative to that at the Equator. The larger the area upon which the beam is spread out, the lower the
