Solution: In a scanning electron microscope the wavelength of the electrons used to image very small objects is 2.74 pm, what is the velocity of the electron in the instrument?  (h =  6.63 x 10 -34 kg•m2/sec; 1

Problem

In a scanning electron microscope the wavelength of the electrons used to image very small objects is 2.74 pm, what is the velocity of the electron in the instrument?  

(h =  6.63 x 10 -34 kg•m2/sec; 1.00 pm = 1.00x10 -12 m, me = 9.11x10 -31 kg; 1J = 1Kg•m2/sec2)
