Diffraction grating Study guides, Study notes & Summaries

PHYS 1260 Exam 4 with correctly explained test. Superposition and Interference - correct answers.- same wave + same wave = reinforcement - two opposite waves = cancellation - two similar waves = partial cancellation - interference patterns of overlapping waves from 2 vibrating sources - interference pattern = caused by interference b/w a pair of waves - constructive interference produces bright region where waves reinforce each other (waves arriving in phase) - destructiv...

Instrumental Analysis ACS Final Prep Exam with Questions and Answers. what are the difference between calibration sensitivity and analytical sensitivity - answercalibration sensitivity is the slope of a calibration curve at the concentration of interest while analytical sensitivity is a response to the noise ratio how to calculate calibration sensitivity - answery=mx+b (m is the calibration sensitivity) graph concentration vs mean analytical signal how to find the analytical sensitivity - ...

CP2 Exam 1 Questions & Answers 2024 In a laboratory experiment, a diffraction grating produces an interference pattern on a screen. If the number of slits in the grating is increased, with everything else (including the slit spacing) the same, then - ANSWER-The fringes stay in the same position but get brighter and narrower. White light passes through a diffraction grating and forms a rainbow pattern on a screen behind the grating. For each rainbow, - ANSWER-the red side is farthest from...

CP2 Exam 1 Questions & Answers 2024 why would a block have 2 reflections of light - ANSWER-reflection from the front and the back of the block how does fringe spacing change when distance between the lists, d, is increased - ANSWER-fringes gets closer what is diffraction - ANSWER-when a wave passes through a small opening it spreads to fill space beyond opening what happens when light travels from air to water - ANSWER-the speed decreases the dark bands in the interference patte...

MMSC407 Exam 1 Questions with Correct Answers albuminuria - Answer--increase in urinary albumin is early sign of renal nephropathy -albumin is a much larger ketone and when it needs to be broken down, the kidneys lose their ability to filter -annual assessment of kidney function by determination of urinary albumin excretion is recommended for diabetic patients -looks at small amounts of albumin (microalbumin = small amounts NOT small in size) -persistent amount of albumin is compared a...

CP2 Exam 1 (Latest) 2024 Questions & Answers Solved 100% Correct!!

You have decreased the acoustic power by -3 dB. Which of the following most accurately describes this adjustment? A. Intensity has been quadrupled B. Intensity has been quartered C. Intensity has been increased 10 times D. Intensity has been halved E. Intensity has not been altered CORRECT ANSWERS: D. Intensity has been halved intensity change of 3 dB corresponds to a doubling of the intensity. if it's changed by -3 dB, intensity is halved. When you switch from a 2.5 MHz to a 5 MH...

MMSC 407 Final Exam questions and answers well illustrated. light - correct energy source that can be characterized in terms of wavelength, amplitude and frequency -the visible spectrum wavelength - correct distance between waves amplitude - correct height of a wave frequency - correct many waves pass in one second (related to speed) high energy waves - correct frequency, very short and compact wavelengths -e.g. violet low energy waves - correct frequency, lon...
