Part A) Suppose the low-energy end of the pulse had a wavelength of 717 nm . What is the wavelength of the high-energy end of the pulse that is limited only by the uncertainty principle?
Part B) What is the energy uncertainty ΔE associated with a short pulse of laser light that lasts for only 3.2 femtoseconds (fs)?

The characteristics of two different types of reactions are shown below: reaction a: electrons are gained by the atoms of an element. reaction b: protons are lost by the atom of an element. which statement is true about the atoms of the elements that participate in the two reactions? their identity changes in both reaction a and reaction b. their identity changes in reaction a but not in reaction b. their identity changes in reaction b but not in reaction a. their identity remains the same in both reaction a and reaction b.
