Assuming that the smallest measurable wavelength in an
experiment is 0.950 fm, what is the maximum mass of an object
traveling at 969 m s ^-1 for which the de Broglie wavelength is
observable?
Assuming that the smallest measurable wavelength in an
experiment is 0.570 fm , what is the maximum mass of an object

wavelength is observable?
When an excited electron in a hydrogen atom falls from n=7n to
n=2, a photon of ultraviolet light is emitted. If an excited
electron in an He+ ion falls from n=5, which energy level must it
fall to (n1) for ultraviolet light of a similar...

1. what is the best wavelength to use to examine the smallest
visible samples? Why?
2. If the resolution of an FTIR depends on the distance the
mirror travels, why are relatively long moving distances such as 2
or 4 cm not used? What is the trade-off?
3. Which of the three contributing factors to band broadening in
chromatography is independend of the flow rate? Explain why.
For your indicator, what is the wavelength of maximum absorbance
for the pH < 4.00 solution? What is the wavelength of maximum
absorbance for the pH > 10.00 solution? What colors correspond
to these wavelengths? How do the observed colors of these solutions
relate to the colors at their absorbance maxima? This is the
procedure:
