Exercise 3. One method used to distinguish between granitic \( (G) \) and basaltic \( (B) \) rocks is to examine a portion of the infrared spectrum of the sun's energy reflected from the rock surface. Let \( R_{1}, R_{2} \), and \( R_{3} \) denote measured spectrum intensities at three different wavelengths. Typically, for granite \( R_{1}
