The experimental evidence that electrons could act as waves was based on quantized wavelengths and diffraction pattern evidence. true or

-

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.

c. heat could easily travel through the molecules in the air and escape/enter the flask. removing the air slows down the heat transfer.
