PHYS 1260 FINAL EXAM 2025/2026 ACTUAL EXAM COMPLETE EXAM QUESTIONS WITH
DETAILED VERIFIED ANSWERS (100% CORRECT ANSWERS) ALREADY GRADED A+
According to Einstein's theory of special relativity Space and time are aspects of each other
Energy and mass are aspects of each other
Heisenberg's uncertainty principle is Noticeable only for submicroscopic particles
A fundamental principle in quantum mechanisms
Predominant in the atomic domain
Quantization is electron energy states in an atom is better understood in terms of the electron's
Wave nature
This discrete radii and energy starts of atoms in an integral number of de Broglie
wavelengths
Which radiation has no association with electric charge? Gamma
Alpha and beta particles are deflected by a magnetic field in opposite directions
Magnetic fields Deflect
,If gamma goes through the field, which way is he deflected? No deflection (direction)
No charge No deflection
For an isotope with a half-life of two days, at the end of four days the amount that remains is
One-quarter
How long is half-life? 2 days
in wave optics, distinction is between coherent and incoherent sources of light
incoherent light lacks a specific direction and has reflectively large delta f
coherent light has a specific direction and a smaller delta f
long coherence length looks more like a generic wave
light from 2 closely spaced stars cannot produce a steady incoherencce pattern due to
incoherence
closely spaced individual coherent sources appear as a single incoherent source
, whether constructive or destructive, interference amounts to a difference in path length
constructive bright
destructive dark
in the double slit experiment, fringes are more widely spaced when illumination is with
monochromatic longer wavelength
when waves from a pair of closely spaced slits arrive in phase a bright fringe is produced
light always travels through a vacuum (empty space)
only the earthbound twin remains in an inertial reference frame continuously and therefore
only his calculations are to be trusted
thin transparent film can produce two coherent, interfering light waves
according to the special theory of relativity, while traveling at a very high speed, your pulse rate
remains unchanged
