- Sodium Emission Spectrum
A. The most prominent line in the emission spectrum of sodium is
the result of a transition from a 3p to a 3s orbital. The...
An analog signal, bandlimited to 20 Hz is corrupted by
high-frequency noise. The spectrum of the noise is from 25 Hz to 35
Hz. The noisy analog signal is sampled at 60 Hz. A digital lowpass
filter is to be designed so as to remove the noise from the signal.
Find the desired frequency response.
What is a blackbody spectrum? What is an emission line spectrum?
What is an absorption line spectrum? How are each created? Which of
these spectra (or which combination of these spectra) best
describes the light coming form the sun?

Method A: Based on the frequency of a simple harmonic
oscillator.
The angular frequency of a mass on a spring is given by
ω=(k/m)1/2ω=(k/m)1/2 where m is the mass and k is the spring
constant. The period of a harmonic oscillator is
T=2π/ωT=2π/ω .
If you do a little math, you can get a formula for the spring
constant in terms of the mass and the period.
a) Design a procedure to measure the spring constant based on
Method A...

(V) Let A ⊆ R, B ⊆ R, A 6= ∅, B 6= ∅ be two bounded subset of R.
Define a set A − B := {a − b : a ∈ A and b ∈ B}. Show that sup(A −
B) = sup A − inf B and inf(A − B) = inf A − sup B
