Question

Diffrence between opic axis and crystallographic axis

Answer 1

Optic axis of a crystal. An optical axis is a direction rather than a single line: all rays that are parallel to that direction exhibit the same lack of birefringence.

Answer 2

Answer:

they can collide with other particles and can be diffracted like light. The wave properties of electrons are easier to observe with experiments than those of other particles like neutrons and protons because electrons have a lower mass and hence a longer de Broglie wavelength for a given energy.
