Wavelength and frequency Study guides, Class notes & Summaries

Waves are classified according to whether or not they need a medium in which to propagate. A wave which needs a medium is called a(n) ______________________ wave, a wave which will propagate in a vacuum (the absence of a medium) is called a(n) ________________ wave correct answer: mechanical, electromagnetic What are the two classifications of mechanical waves? correct answer: Transverse and longitudinal Frequency has the units of: (select all that apply) A. Cycles/second B. Hz C. Her...

Discuss the basics of radiologic science CORRECT ANSWER X-rays fall between the gamma ray and ultraviolet wavelength range; xrays have between 0.03 to 3 nanometer wavelengths. (associated with short wavelengths) Describe how xrays are produced CORRECT ANSWER Xrays are the result of a high impact of a large volume of heated negatively charged electrons with a hard surface. When this impact occurs, the electrons rupture with the conversion of electrons to x-radiation. Describe the elements o...

MMSC407 Final Exam Questions with Correct Answers Describe the characteristics of light as an energy source. - Answer-1. Wavelength - the distance between the crests of two successive waves 2. Amplitude - the height of each wave 3. Frequency - the number of waves which pass an observation point in one second In terms of energy: -High energy = high frequency, short wavelength -Low energy = low frequency, long wavelength Describe the relationship between percent transmittance and abso...
