a. transverse wave - draw & label crest, trough, amplitude, and wavelength.

b. longitudinal wave - draw & label compression, rarefaction, and wavelength.

part 2: match the vocabulary

1. reflection
2. refraction
3. diffraction
4. absorption
5. interference

a. waves bend as they enter a medium
b. waves bounce off a surface
c. waves spread out after an opening
d. energy is taken in by
e. waves combine to

Explanation:

For the "Match the Vocabulary" part:

1. Reflection: Waves bounce off a surface (matches B).
2. Refraction: Waves bend as they enter a medium (matches A).
3. Diffraction: Waves spread out after an opening (matches C).
4. Absorption: Energy is taken in (matches D).
5. Interference: Waves combine (matches E, assuming E is "Waves combine to form...").

For the "Label the Waves" part:

• Transverse Wave: Draw a wave with peaks (crests) and troughs. Label crest (highest point), trough (lowest point), amplitude (distance from rest to crest/trough), wavelength (distance between two crests/troughs).
• Longitudinal Wave: Draw a series of compressions (close - together regions) and rarefactions (spread - out regions). Label compression, rarefaction, and wavelength (distance between two compressions/rarefactions).

Answer:

Part 1: Label the Waves

A. Transverse Wave

• Draw a wave with oscillating motion perpendicular to the direction of wave travel.
• Label:
• Crest: The highest point of the wave.
• Trough: The lowest point of the wave.
• Amplitude: The vertical distance from the rest position (middle line) to a crest or trough.
• Wavelength: The horizontal distance between two consecutive crests or two consecutive troughs.

B. Longitudinal Wave

• Draw a wave with oscillating motion parallel to the direction of wave travel, showing regions of compression (where particles are close together) and rarefaction (where particles are far apart).
• Label:
• Compression: The region where particles are densely packed.
• Rarefaction: The region where particles are spread out.
• Wavelength: The distance between two consecutive compressions or two consecutive rarefactions.
