Answer 2

Answer: 5:27

Explanation

According to Plancks quantum theory .

E is directly proportional to frequency

And frequency is inversely proportional to wavelength

Then,

Energy of quantum is inversely proportional to wavelength.

That means electron of lower energy have maximum wavelength.
