I. A ray of light strikes the surface at a rectangular glass slab such that the angle of incidence is a. 0o
b. 45o.
In each case, draw a diagram to show the path taken by the ray as it passes through the glass slab and emerges from it. ​

The horse latitudes-high-pressure zones about 30 degrees north and 30 degrees south of the equator.-warm air traveling away from the equator cools and sinks-weather tends to be clear and drythe doldrums-low-pressure near equator-air rises and spreads out toward the poles-rising moist air produces clouds and heavy rainthe westerlies-blow from the west-move from the horse latitudes toward the poles.-bring storms across much of the united statesthe tradewinds-blow from the east-move from the horse latitudes toward the equator  -strong, steady winds

The answer is  a.first and third quarters
