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:
= (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.

Answer:
[Kr] 4d² 5s²
Explanation:
In group 2 and period 2 is the element Zirconium. Here's an example A noble gas configuration of an atom consists of the elemental symbol of the last noble gas prior to that atom, followed by the configuration of the remaining electrons. So for sodium, we make the substitution of [Ne] for the 1s22s22p6 part of the configuration. Sodium's noble gas configuration becomes [Ne]3s1.
