a. what is the difference between a flourescence
excitation spectrum and a fluorescence emission spectrum?. which
resembles an absorption spectrum.
b. consider a molecule that can fluoresce from the s1
state and phosphoresce from the t1state. which is emitted at longer
wavelength?make a sketch showing absorption fluorescence and
phosphorescence on a single spectrum.
a. State the difference between personal frequency and
excitation frequency
b. State the difference in angular frequency and linear
frequency
c. State the difference between transient response and steady state
response
d. Mention the different meanings of eigenvalue and eigenvector in
the vibration equation
e. Mention the difference between viscous and silencer d
The frequency of light reaching Earth from a
particular galaxy is 16% lower than the
frequency the light had when it was emitted.
(b) What is the speed of this galaxy relative
to the Earth? Give your answer as a fraction of the speed of
light.
c
If you could show your work as well that'd be
awesome! Thank you!
The frequency of light reaching Earth from a particular galaxy
is 18% lower than the frequency the light had when it was emitted.
a) explain whether the galaxy is moving toward or away from earth.
b) What is the speed of this galaxy relative to the Earth? Give
your answer as a fraction of the speed of light.
a) Assuming that the frequency of oscillation is due to the
difference in energy between the 2p and 1s states of the H atom,
and that the amplitude of oscillation is about one Bohr radius,
estimate the rate at which energy is classically radiated in
eV/s.
b) Estimate the classical time it takes for this atom to radiate
the energy difference between these two states.
