Question

wavelength vs. frequency of a string
which statements accurately describe the graph?
check all that apply.
the dependent variable, frequency, is placed on
the horizontal axis.
the intervals on each axis are evenly spaced.
the vertical axis is labeled \wavelength\ and uses
meters for units.
a smooth curve is drawn through the data points.
a best - fit line is drawn through the data points.

Explanation:

• For the first option: The dependent variable should be on the vertical axis. Here, wavelength (dependent as it depends on frequency) is on vertical, so this option is wrong.
• For the second option: Looking at the x - axis (frequency) and y - axis (wavelength), the intervals are evenly spaced. For example, on the x - axis, the intervals between 50, 100, 150 etc. are 50 units each.
• For the third option: The vertical axis is labeled “wavelength” and the unit is meters (m) as shown on the y - axis.
• For the fourth option: A smooth curve (not a straight best - fit line) is drawn through the data points as per the graph.
• For the fifth option: It is a curve, not a best - fit (straight) line.

Answer:

The intervals on each axis are evenly spaced.
The vertical axis is labeled “wavelength” and uses meters for units.
A smooth curve is drawn through the data points.
