Question

ch9. q1
the wavelike properties of electrons are useful in ____.
writing electron configurations
magnifying objects
deflecting photons
determining the velocity and position of a particle

Explanation:

Electron microscopes use the wave - like properties of electrons. Electron microscopes can achieve much higher magnification than light microscopes. Writing electron configurations is based on electron - filling rules. Deflecting photons is not related to electron wave - like properties. The Heisenberg uncertainty principle (which is related to wave - particle duality but not directly for magnification) states that we cannot simultaneously determine the velocity and position of a particle accurately.

Answer:

magnifying objects
