Describe the three (3) exceptions to employment at will. Just cause. Discrimination. Public policy. Describe constructive discharge. Constructive dismissal, also called constructive discharge or constructive termination, occurs when an employee resigns as a result of the employer creating a hostile work environment. What is an example of constructive discharge? A manager who says, "I'm going to make your life here so miserable that you'll quit," then proceeds to do just that. Descr...

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...

CEM 141 PASSED Exam Questions and CORRECT Answers Evidence that light is a wave - Ans Light is a wave because when light goes through 2 slits a diffraction pattern occurs. Reasoning that light is a wave - Ans the waves from each slit meet "in phase" or "out of phase" when the waves meet in phase constructive interference occurs and the wave intensity increases. this is seen by bright spots in the patterns. when the waves meet out of phase destructive interference occurs and the w...
