why did scientists using classical, newtonian physics have difficulty explaining the photoelectric effect
zzz [600]

The correct answer is :

According to classical electrodynamics, light energy is a wave that is absorbed by atoms in a manner similar to how an object absorbs radiant heat. So, the atoms of a metal would absorb more energy the brighter the light was. It would be feasible for an electron in a metal to break free from its atoms if it received enough energy from the incoming wave. The more energy absorbed, the more energetic the metal's released electrons would be. Additionally, no electrons could conceivably be ejected until each atom had enough light energy. Light intensity was far more important than light frequency.

In many respects, the photo-electric effect contradicted this strategy:

  • If the light was below a specific frequency, no matter how bright it was, no electrons were released. Increased light intensity increased the number of electrons that were released, but not their energy, if the light was above this frequency.
  • Regardless of how weak the light was, electrons were nearly immediately emitted from the metal.
  • Even though the intensity of the light was reduced, an increase in its frequency led to more energising electrons leaving the metal.

(Write the answer in fair test) You have to investigate whether surface area affects how fast some water evaporates
Damm [24]

Answer:

Evaporation increases with an increase in the surface area

If the surface area is increased, then the amount is of liquid that is exposed to air is larger. More molecules can escape with a wider surface area.
