purple/violet

400

What are waves where the particles move perpendicular (up and down) to the direction of motion?

transverse waves

400
What is the distance (how high or how low) particles move from the baseline of the wave?
amplitude
400

A wave with an amplitude of 2cm interferes with a wave of amplitude -2cm traveling in the opposite direction. What is the amplitude of the resultant wave?

500

A wave is being generated on a string with a velocity of 5 m/s. If the wavelength is halved, what will the new velocity be?

5 m/s. The frequency will change, not the velocity.
