Question

✨❤explain stark effect to a student who has only 10th grade knowledge✨❤

Answer 1

Answer:

When electrons are excited they gain energy and are elevated to higher orbits or shells.

But the higher energy state is very unstable. So the electron comes back to its original lower energy shell.

This transfer releases energy in form of electromagnetic waves.

Electromagnetic waves form pattern in the projection screen. The pattern is in the form of straight parallel lines.

Now comes the STARK EFFECT.

Stark effect refers to splitting of those line in the projection screen in presence of electric field.

In other words, during STARK EFFECT, the shells undergo splitting to form smaller units called orbitals. Orbitals are the regions having maximum probability of presence of electron.
