How to Decrease Deflection of Electrons?
🔴 SCENARIO 1:
someone said, the answer is C because increasing the the p.d of anode will accelerate the electrons, and when electrons get accelerated they move fast, getting less time to deflect.
so i used the same logic in
🔴SCENARIO 2:
with that same logic, shouldn't be the answer for this question be option D? increasing p.d of the plates will make the electrons more attracted to the plates, so this will accelerate them and make the move more quickly, giving them less time to deflect.

These two questions are looking at different behaviours of electrons, wave like behaviour and particle like behaviour.
The first question is looking at wave-like behaviour, diffraction. The crystal is acting like a diffraction grating and the electrons are acting like waves with wavelengths given by deBroglie's equation λ=h/mv
The second question is looking at particle-like behaviour, electrons are being accelerated vertically by an electric field between the plates.
if the electric field strength is increased the electrons will be accelerated vertically at a greater rate and if the electrons spend longer between the plates they will be accelerated for a longer time and leave the plates having been displaced vertically further.

thank you so much!! may you have an easy-going good day
