The scientist is using gel electrophoresis. Gel electrophoresis is a process used to cut DNA into fragments in order to see them.
The frequency of a wave can be calculated using the wavelength and and speed of light. The frequency of a wave with 225 nm is 1.33 × 10¹⁵ Hz.
<h3>What is frequency ?</h3>
Frequency of a wave is the number of wave cycles per second. It mathematically taken as the inverse of time taken to travel and it have a unit of s⁻¹ other than Hz.
The wavelength of an electromagnetic wave is the distance between two consecutive crests or troughs.Wavelength and frequency are in inverse relationship. For a longer wavelength the frequency will be lower.
Higher frequency waves are more energetic than longer wavelengths. Thus energy and frequency are in direct proportion
It is given that the wavelength of the electron is 225 nm. Consider the electron behaving as wave and the frequency v can be calculated using the speed of light c as follows:
![v = C/\lambda](https://tex.z-dn.net/?f=v%20%3D%20C%2F%5Clambda)
= (3 ×10⁸ m/s) /(225 ×⁻⁹ m)
= 1.33 × 10¹⁵ Hz.
Hence, the frequency of an electron with a wavelength of 225 nm is 1.33 × 10¹⁵ Hz.

I'm adding a ton of characters down here so they let me post my answer.
Answer:
Al is oxidized to Al3+ and Zn2+ is reduced to Zn
Explanation:
Al loses 3 electrons to form Al3+ and Zn gains 2 electrons and reduces to Zn 2+
