The average kinetic energy of a particle at a temperature of T is 3/2 kBT(Section 10.5). What is the wavelength of an electron at 20oC? How about a proton at the same temperature?
Answer to relevant QuestionsAn electron microscope is an instrument that uses electrons instead of light for the imaging of objects. A mono-chromatic beam of electrons is accelerated through a potential difference of 50 V. What is the ratio of the ...Electrons are accelerated from rest through an electric potential difference. (a) If this potential difference increases to four times the original value, the new de Broglie wavelength will be (1) four times, (2) twice, (3) ...What are the (a) Half-life (b) Decay constant for a stable isotope? PET scans require extremely fast computers coupled with gamma- ray detectors capable of accurate energy measurements. Explain why both energy accuracy and comparison of arrival times are crucial to the success of a PET scan. Complete the following nuclear decay equations by filling in the blanks:
