The prediction about the waves if they were to crash into each other is that The resulting wave would travel at 4.2 hertz.
<h3>What is the wave about?</h3>
Note that:
Constructive interference of the waves is one that leads to an increase in amplitude or frequency of any kind of waves.
Hence:
F' = 3 Hz + 1.2 Hz
= 4.2 Hz
Destructive interference of the waves is one that lowers the amplitude or frequency of waves and as such:
F' = 3 Hz - 1.2Hz = 1.8 Hz
The prediction about the waves if they were to crash into each other is that The resulting wave would travel at 4.2 hertz.

The code chunk that lets the analyst create the phone_number column is: unite(customers, "phone_number", area_code, phone_num, sep="-"
<h3>What is a data frame?</h3>
A data frame refers to a two-dimensional array-like structure or table that is made up of rows and columns, which is typically used for storing data in R Studio using the R programming language.
In Computer programming, a data frame is a list of vectors that are all equal in length, and each column consist of values of one variable while each row consist of a set of values from each column.
<h3>The executable code in R Studio.</h3>
In this scenario, the code chunk that would be used to create a data frame that combines the two columns into a single column (phone_number) is:
- unite(customers, "phone_number", area_code, phone_num, sep="-"
