Lecture 7: Atomic Spectra & the Bohr Model Flashcards
1
Q
Blackbody Radiation
A
Matter emits light only in
quantized amounts (E=hν)
2
Q
Photoelectric effect
A
Light itself is quantized – it exists in ‘wave packets’ called photons E=hv = hc/λ
3
Q
Spectrum
A
a set of wavelengths(λ)
4
Q
Continuous spectrum
A
all wavelengths are present (in the given range)
5
Q
from earth, sunlight is not
A
a continuous spectrum
6
Q
balmer series
A
Visible lines in the H atom spectrum are called the
7
Q
Bohr proposed the idea that
A
the energy of electrons is quantized
8
Q
free electron
A
An electron with zero energy
9
Q
distinct spectral lines exist because of
A
electrons jumping between energy levels in the atom
