The diagram represents a standing wave.  The number of nodes and antinodes shown in the diagram is:

• 5 nodes and 6 antinodes
• 6 nodes and 5 antinodes
• 4 nodes and 5 antinodes
• 6 nodes and 10 antinodes

Wave X travels eastward with frequency f and amplitude A.  Wave Y, traveling in the same medium, interacts with wave X. This produces a standing wave.  Which statement about wave Y is correct?

• Wave Y must have a frequency of f, and Amplitude of A, and be traveling westward.
• Wave Y must have a frequency of 2f, and amplitude of 3A, and be traveling eastward.
• Wave Y must have a frequency of 3f, an amplitude of 2A, and be traveling westward.
• Wave Y must have a frequency of f, an amplitude of A, and be traveling eastward.

When a light wave enters a new medium and is refracted, there must be a change in the light wave's

• speed
