VERIFIED ANSWERS ALREADY GRADED A+ (BRAND NEW VISION)
Quantization is electron energy states in an atom is better understood in terms of the electron's
- answersWave nature
This discrete radii and energy starts of atoms in an integral number of - answersde Broglie
wavelengths
Which radiation has no association with electric charge? - answersGamma
Alpha and beta particles are deflected by a magnetic field in - answersopposite directions
Magnetic fields - answersDeflect
If gamma goes through the field, which way is he deflected? - answersNo deflection (direction)
No charge - answersNo deflection
For an isotope with a half-life of two days, at the end of four days the amount that remains is -
answersOne-quarter
How long is half-life? - answers2 days
in wave optics, distinction is between - answerscoherent and incoherent sources of light
incoherent light - answerslacks a specific direction and has reflectively large delta f
,coherent light - answershas a specific direction and a smaller delta f
long coherence length - answerslooks more like a generic wave
light from 2 closely spaced stars cannot produce a steady incoherencce pattern due to -
answersincoherence
closely spaced individual coherent sources appear as - answersa single incoherent source
whether constructive or destructive, interference amounts to a - answersdifference in path
length
constructive - answersbright
destructive - answersdark
in the double slit experiment, fringes are more widely spaced when illumination is with
monochromatic - answerslonger wavelength
when waves from a pair of closely spaced slits arrive in phase - answersa bright fringe is
produced
light always travels through a - answersvacuum (empty space)
only the earthbound twin remains in an inertial reference frame continuously and therefore -
answersonly his calculations are to be trusted
, thin transparent film can produce - answerstwo coherent, interfering light waves
according to the special theory of relativity, while traveling at a very high speed, your pulse rate
- answersremains unchanged
comparing the lgiht from a glowing tube of neon gas and the beam of a helium-neon laser,
there is a greater number of spectral lines in light from the - answersneon gas tube
associtaed with the particle would be a wave with a wavelength called the - answersde Broglie
wavelength
quantum indicates - answersdual-personality
according to Louis de Broglie, a material particle has - answersparticle properties and wave
properties
the more we know about a particle's position, the less we know about its - answersspeed,
momentum and kineitc energy
a given set of quantum numbers makes explicit the - answersallowed states of the hydrogen
atom
the principle quantum number, n, specifies - answersthe average distance of the electron from
the nucleus and can have any positive integral value
the orbital quantum number, l, specifies - answersthe degree to which the electron cloud
differs from a spherically symmetric distribution and can have any of the values related to the
values of n
