AS102 Study Guide - Final Guide: Radio Wave
Document Summary
Each of these graphs plots intensity of the light versus wavelength of the light. In the middle of the horizontal axis is the visible part of the spectrum (the light to which our eyes are sensitive). To the left of this visible part are gamma rays and x-rays; to the right is the infrared, microwave and radio wave part of the spectrum. The top graph shows an object (a star, say) which peaks in the blue part of the spectrum so this object gives off more blue light than red light and, therefore, appears blue to us. The lower graph shows an object whose temperature is about 5000 k (a little cooler than our sun) and it peaks in the upper red part of the spectrum so it would probably look orange in colour. So, all you cool cats taking as102 have a body temperature of about 310 k (about.
