Two Different Electron Beams Are Incident on Two Different Targets

question 51

Multiple Choice

Two different electron beams are incident on two different targets and both produce x rays.The cutoff wavelength for target 1 is shorter than the cutoff wavelength for target 2.We can conclude that:

• A)target 2 has a higher atomic number than target 1
• B)target 2 has a lower atomic number than target 1
• C)the electrons in beam 1 have greater kinetic energy than those in beam 2
• D)the electrons in beam 1 have less kinetic energy than those in beam 2
• E)target 1 is thicker than target 2
