Question

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.

Answer 1

Correct choices: 2, 3, and 4.

- (1) False — the dependent variable (frequency) should be on the vertical axis, not the horizontal.
- (2) True — the tick marks on both axes are evenly spaced.
- (3) True — the vertical axis is labeled “wavelength” with units in meters.
- (4) True — a smooth curve is drawn through the data points.
- (5) False — there is no straight best-fit line; the data are fit with a smooth curve.
