have allowed greater use of the electromagnetic spectrum 1. describe electromagnetic waves in terms of their speed in space and their lack of requirement of a medium for propagation In space (a vacuum) electromagnetic waves travel at the speed of light‚ a constant equal to 3.00108ms1. Unlike sound waves‚ electromagnetic waves do not vibrate particles‚ therefore they do not need a medium (substance) to propagate (move). 2. identify the electromagnetic wavebands filtered out by the atmosphere‚

This can be an extreme fire hazard and can endanger all the people in your building. Purchase fake candles‚ as they can do the trick if you need extra light at night.

decapitating a middle-age man in his bed with the aid of an old woman. The elegantly dressed female using a sword to behead the man is named Judith. The male figure in the painting is Holofernes‚ as the title states. The old woman‚ who is wearing a light-colored turban and green dress with a yellow coat‚ is a servant of Judith based on her unrefined clothing. She is holding several lighted candles on her left hand and grasping Holofernes’ struggling hand with her right hand. The rectangular shape

Light Amplification by Stimulated Emission of Radiation LASERS Laser Fundamentals • A laser is a device that generates light by a process called STIMULATED EMISSION. • The acronym LASER stands for Light Amplification by Stimulated Emission of Radiation. • The light emitted from a laser is monochromatic. • Laser emit light that is highly directional. • The light from a laser is said to be coherent. Laser Operation: Excited State Energy Introduction Metastable State Spontaneous Energy

if we know the structure of the grating‚ we can deduce properties about the incident light‚ in particular its wavelength. This will be our task‚ in this first optics lab exercise. The analysis of diffraction patterns is used extensively in the sciences to provide information about the microscopic structure of molecules‚ atoms‚ and nuclei. In addition to various forms of light (gamma rays‚ x-rays‚ visible light‚ infra-red‚ radio waves)‚ even high-energy atomic and sub-atomic particles (electrons

calibration curve. Colorimetry measures the absorption of light at wavelengths within the visible region of the electromagnetic spectrum. It can be used to identify the unknown concentration of a solution in reference to a solution of a known concentration. When a solution appears coloured‚ you see the colour that has not been absorbed by the molecules. A light beam is passed through a sample inserted into a colorimeter‚ the light is split into two beams‚ one being absorbed by the sample‚ the
