<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:

Explanation:
It can be predicted that the light beam will follow a stream of water as it flows out of a bottle.
<h3>How does light follow water?</h3>
When a light beam passes from the medium of water, then it reflects and change its direction due to become slow compare to air.
In the air and water the light travels from the stream of water, but the difference is that in water it bends, and the speed slows down. This stream of water is act similar to the optical fiber.
Hence, it can be predicted that the light beam will follow a stream of water as it flows out of a bottle.
