In the diagram which letters represent the nodes

• A B C

• A C E

• B D

• B D E

• A C D

The moving black dot is called:

• a node
• an anti-node
• an anti-amplitude
• the wangy bit

The stationary dot is called:

• a node.
• an anti-node.
• the amplitude.
• the not moving bit.

Which harmonic is shown?

• 1st
• 2nd
• 3rd
• 4th

How many antinodes does this standing wave have?

• 5

• 6

• 7

• 8

The first harmonic has

• 1 antinode

• 1 node

• 2 antinodes

• no nodes

The second harmonic on a string fixed at both ends shows

• A wavelength

• Half a wavelength

• Two wavelengths

A wave in which the particles of the medium move perpendicularly to the direction the wave is traveling

• A. surface wave
• B. transverse wave
• C. electromagnetic  wave
• D. longitudinal wave

When two waves combine to form a new wave with a smaller amplitude, it is called 

• Constructive Interference
• Destructive Interference

The figure represents a string of length L, fixed at both ends, vibrating in several harmonics. Which string shows the 4th harmonic?
