question: CHAPTER XIII 

Four men were discussing the verdict at the adjourned inquest upon Victor Bidlake, at Soto's American Bar about a fortnight later. They were Robert Fairfax, a young actor in musical comedy, Peter Jacks, a cinema producer, Gerald Morse, a dress designer, and Sidney Voss, a musical composer and librettist, all habitues of the place and members of the little circle towards which the dead man had seemed, during the last few weeks of his life, to have become attracted. At a table a short distance away, Francis Ledsam was seated with a cocktail and a dish of almonds before him. He seemed to be studying an evening paper and to be taking but the scantiest notice of the conversation at the bar. 

"It just shows," Peter Jacks declared, "that crime is the easiest game in the world. Given a reasonable amount of intelligence, and a murderer's business is about as simple as a sandwich-man's." 

"The police," Gerald Morse, a pale-faced, anaemic-looking youth, declared, "rely upon two things, circumstantial evidence and motive. In the present case there is no circumstantial evidence, and as to motive, poor old Victor was too big a fool to have an enemy in the world." 

Sidney Voss, who was up for the Sheridan Club and had once been there, glanced respectfully across at Francis. 

"You ought to know something about crime and criminals, Mr. Ledsam," he said. "Have you any theory about the affair?" 

Francis set down the glass from which he had been drinking, and, folding up the evening paper, laid it by the side of him.

question: Infrared radiation is used in industrial, scientific, and medical applications. Night-vision devices using active near-infrared illumination allow people or animals to be observed without the observer being detected. Infrared astronomy uses sensor-equipped telescopes to penetrate dusty regions of space, such as molecular clouds; detect objects such as planets, and to view highly red-shifted objects from the early days of the universe. Infrared thermal-imaging cameras are used to detect heat loss in insulated systems, to observe changing blood flow in the skin, and to detect overheating of electrical apparatus. 

The onset of infrared is defined (according to different standards) at various values typically between 700 nm and 800 nm, but the boundary between visible and infrared light is not precisely defined. The human eye is markedly less sensitive to light above 700 nm wavelength, so longer wavelengths make insignificant contributions to scenes illuminated by common light sources. However, particularly intense near-IR light (e.g., from IR lasers, IR LED sources, or from bright daylight with the visible light removed by colored gels) can be detected up to approximately 780 nm, and will be perceived as red light. Sources providing wavelengths as long as 1050 nm can be seen as a dull red glow in intense sources, causing some difficulty in near-IR illumination of scenes in the dark (usually this practical problem is solved by indirect illumination). Leaves are particularly bright in the near IR, and if all visible light leaks from around an IR-filter are blocked, and the eye is given a moment to adjust to the extremely dim image coming through a visually opaque IR-passing photographic filter, it is possible to see the Wood effect that consists of IR-glowing foliage.
1. what doesn't have a precise definition?
****
answer: 1. the boundary between visible and infrared light


question: Alice needs some money for a Mother's Day present. She tells her father about her problem. "I'll pay you to do some housework. You can clean up the yard ," her father says.
