Vector Fields Quiz

What is a vector field?

• A graphical representation of data.

• A mathematical function that associates a vector with each point in space.

• A mathematical function that associates a scalar with each point in space.

• A type of chart used in statistics.

Which of the following is NOT an application of vector fields?

• Fluid dynamics

• Linear regression

• Weather forecasting

• Electromagnetics

What do arrow plots (quiver plots) represent in vector fields?

• The direction and magnitude of the vectors.

• The divergence of the vector field.

• The scalar potential of the vector field.

• The magnitude of the vectors only.

What are streamlines used for in vector field visualization?

• To create three-dimensional representations.

• To visualize scalar fields.

• To show the flow path of the vector field.

• To represent the magnitude of the vectors.

What is the main advantage of using color maps in vector field visualization?

• They are easy to interpret.

• They can visualize large-scale fields effectively.

• They represent direction clearly.

• They are suitable for small-scale fields.

What do vector tubes represent in three-dimensional vector fields?

• The magnitude of the vectors only.

• The direction of the vectors only.

• Both magnitude and direction of the vectors.

• The scalar potential of the vector field.

Which technique is used to visualize the internal structure of vector fields?
