task. Here‚ THz technology can provide a valuable contribution. KEYWORDS: - THz technology‚ THz spectroscopy‚ THz sciences. I. INTRODUCTION The term ‘T-rays’ was coined in the early 1990’s by Bell Labs to describe the spectrum in the Terahertz range (1 THz = 1012). [1] The terahertz region of the spectrum lies on the border of where electronics and optics meet between the mm-wave and infrared bands (100 GHz-10 THz). THz wave could handle ultra broad band signals ‚ have very large absorption

spectrophotometric analysis of copper sulphate Introduction: In the modern usage. The term spectroscopy includes a large group of techniques which differ widely in their mode of application and information they reveal. As a useful working definition‚ spectroscopy is a study of interaction of electromagnetic radiation with matter in the experiment it means it’s the usage of ultra-light to measure the absorbance of the copper sulpate. The regions of the electromagnetic spectrum immediately adjacent

Microwaves (3:04) 7. Where are Microwaves found on the electromagnetic spectrum? Microwaves have wavelengths ranging from 30 centimeters down to 1 millimeter. Microwaves fall between radio waves and infrared waves. 8. Describe one thing that C‐Band Microwaves are used for? Medium length C-Band Microwaves are used for revealing the Earth’s surface. 9. What did two scientists discovered by accident using L‐Band Microwaves? The two scientists

to intensify human sight under very low light conditions. Although more human activities are done during the day than night‚ the capability to see in the dark is still significant in many occasions. Night vision devices focuses infrared light to objects in the dark; infrared is beyond spectrum visible to the human eyes. A device for night vision was perfected during wartime giving soldiers in the battle field a technical benefit over their enemies. Vision equipment has evolved from bulky optical

Experiment 36: Determination of the Structure of a Natural Product in Anise Oil Purpose: The purpose of this experiment is to isolate the major component of anise oil and determine its identity and structure using melting point determination and IR spectroscopy. Introduction: The major component of anise oil has the chemical formula C10H12O. This compound is said to be hydrogen deficient‚ meaning that it contains less hydrogen atoms than would be needed for each of the carbon atoms to have the maximum
