Answer 1

Here are the answers and brief explanations for the parts I can complete without the diagrams:

7. Match the term to its definition
A. trough — the lowest part of a transverse wave
B. crest — the highest point of a transverse wave
C. wavelength — the distance between two corresponding points on a longitudinal (or transverse) wave (e.g., from compression to compression or crest to crest)
D. rarefaction — the part of a longitudinal wave that is spread apart
E. frequency — the number of waves that pass a given point in a given time
F. compression — the part of a longitudinal wave that is pressed together

18. Which statement is false?
c and d are false.
- Correct facts: Longitudinal waves move parallel to the disturbance (so statement c is wrong). Transverse waves move perpendicular to the disturbance (so statement d is also wrong). Statements a and b are true in the usual contexts (sound is longitudinal and needs a medium; many transverse EM waves do not require a medium).

19. This wave is stronger than visible light but weaker than an x-ray.
Ultraviolet (UV)

20. The frequency of the ultraviolet wave is (stronger or weaker) __stronger__ than visible light.
(UV has higher frequency than visible light.)

21. Label the parts of this wave (word bank: crest, wavelength, trough, rest point, amplitude)
Without seeing your specific diagram I’ll give the usual placement:
1. crest
2. wavelength
3. trough
4. rest point (equilibrium line)
5. amplitude (distance from rest point to crest or to trough)

22–25. I can’t unambiguously answer the remaining questions because they refer to diagrams (label this wave, choose which diagram shows lowest frequency / loudest sound / highest pitch). Please either upload the diagrams or describe them (how many cycles, spacing, amplitudes, whether they are transverse or longitudinal). With the images or descriptions I will label them and pick the correct choices.
