Laila Monroe · Answer 1

Answer: -

When electrons are fired at an element, the resulting interference pattern is called electron diffraction.

Electrons get scattered on hitting and they are observed via a luminescent screen. The pattern of scattered electrons is consistent with wave behavior like that of X rays.

The experimental evidence that electrons could act as waves was based on quantized wavelengths and diffraction pattern evidence is therefore correct.

Amanda Spears · Answer 2

True

Explanation:

There was a theory proposed by the French physicist Louis de Broglie in 1923. This theory basically states that particles that are studied in quantum mechanics (for example, electrons and light), exhibit properties that can be seen when studying both particles, and waves. This theory was called Wave-Particle Duality.

When studying electrons, they were observed to behave like particles in certain experiments, however, in other experiments they also behaved how a wave would. We think of electrons as particles, which have mass, but they can also be diffracted like electromagnetic waves.
