Try this first
Which factor is crucial for improving the resolution of an electron microscope?.
- A.Increasing the electron beam current
- B.Using a higher voltage to accelerate electrons
- C.Cooling the microscope environment
- D.Using thicker samples
Model answer
What a good answer should say
- Using a higher voltage to accelerate electrons
Explanation
Why this works
Increasing the voltage used to accelerate electrons reduces their wavelength, which in turn improves the resolution of the electron microscope, allowing for finer details to be observed.
