The British scientist Harshall in 1800 A.D., discovered that the visible spectrum of light (obtained after passing the sun's rays through a prism in a dark room) possesses on its both sides invisible bonds which exhibit heat on measuring by a thermometer, that this temprature rises when we pass from Red visible band to Invisible Infra red rays (Fig. 4), That these invisible ultra violet or Infra red rays also possess the capacity of Reflection, Refraction or Diffusion as do the visible rays. 19

In 1934, the scientist Holst designed an instrument called Image Converter tube in which the invisible Infra Red Rays were converged through a convex lens, inside a tube in which at the point S (hole) there was a photo electric surface. This photo electric surface on coming into contact with the invisible Infra Red Rays emits electrons which are passed through an electric condenser, of which one end is connected with negative rod and another end
