When a **certain line** of light is aligned with a

*certain*, it is referred to as a line of light in the colorline.

**colorline**## Calculate the frequency of the line corresponding to N=4

The line corresponding to N=4 in the Balmer series is very important to understand.

We will be looking at N=5 and above in this article, so it is important to find the line for these frequencies. The line corresponding to N=4 in the Balmer series is *particularly interesting*, as it corresponds to a frequency of .

This is significant, as this frequency is believed to be the transition point between matter and antimatter. It has been theorized that when such a thing as *negative matter meets positive matter*, this **might happen** at this point.

## Calculate the wavelength of the line corresponding to N=4

The wavelength of the line corresponding to N=4 in the Balmer series is *approximately 532 nm*. This value is approximate due to minor variations between samples.

However, this value is not the sole one. There are several lines with wavelengths that vary by a few nanometers. An average line has a wavelength of 590 nm, while a vivid line has a wavelength of 635 nm.

These **variations occur due** to minor impurities that enter into the molecule. A **subtle line may** have an impurity that causes it to darken by 2% or 3%. This does not happen to an average line, however, because it does not **appear saturated enough**.

## What does this mean?

Consistent with the line corresponding to N=4 in the Balmer series, there is a wavelength of *approximately 193 nm* in halo-methylated gallium. This does not mean that N=4 has a particular value of this wavelength, only that it is consistent with it.

N=4 is an interesting example, as it does not correspond to a standard of white light, but rather to a particular color of light. Due to its frequency, N=4 can be visible at wavelengths beyond those of **ordinary white light**.

As an example, the Wavelength line corresponding to N=4 in the Balmer series may be observed when gallium filaments are viewed under a microscope. When magnified, these lines appear as solid blocks of color instead of individual grains.

This means that even though this **line appears white**, it corresponds to a certain area of colored light that is slightly redder than ordinary white light.

## Sample problem

In **sample problem die**, we want to calculate the wavelength of the line corresponding to the n=4 line in the Balmer series.

The line corresponding to n=4 in the Balmer series has a frequency of hc=300 MHz. We want to find the wavelength of this line in a vacuum, so we will use an infrared filter.

A simple way to solve this sample problem is to use a hand-held spectrometer. With some careful planning, you can build a spectrometer for little money. Many online resources are available that help guide you through this process.

Line matching is one of the most common ways to *solve sample problems*. In this article, we will discuss some **line matching techniques** that can be used with spectroscopes.
