Chemistry: a molecular approach chapter 7 Exam Questions and Correct Answers

Chemistry: a molecular approach chapter 7 Exam Questions and Correct Answers -mechanical model - Correct Answer A model that explains the strange behavior of electrons. Electromagnetic radiation - Correct Answer A type of energy embodied in oscillating electric and magnetic fields. Amplitude - Correct Answer The wave is the vertical height of a crest (depth of a trough). Wavelength - Correct Answer The wave is the distance between adjacent crests (or any two analogous points) and is measured in units such as meters, micrometers, or nanometers. Frequency - Correct Answer The number of cycles (or wave crests) that pass through a stationary point in a given period of time. Electromagnetic spectrum - Correct Answer Visible light makes up only a tiny portion of the entire electromagnetic spectrum which includes all wavelengths of electromagnetic radiation Gamma rays - Correct Answer The form of electromagnetic with the shortest wavelength X-rays - Correct Answer Electromagnetic radiation with wavelengths slightly longer than those of gamma rays Ultraviolet radiation - Correct Answer Electromagnetic radiatiin slightly smaller wavelengths than visible light Visible light - Correct Answer Ranging from violet (shorter wavelength, higher energy) to red ( longer wavelength, lower energy). Infrared radiation - Correct Answer Electromagnetic radiation emottef from warm objects with wavelengths slightly larger than thos of visible light Microwaves - Correct Answer Electromagnetic radiation with wavelengths slightly longer than those of infrared radiation Radio waves - Correct Answer The form of electromagnetic radiation with the longest wavelengths radiation and smallest energy
