Question
- A. longitudinal waves: process reasoning for Transverse and longitudinal waves
- B. longitudinal waves: a generic revision instruction without the wave idea
- C. longitudinal waves: the opposite relationship from Transverse and longitudinal waves
- D. longitudinal waves: a different Unit 4.6 idea not named in the question
Answer
The correct answer is longitudinal waves: process reasoning for Transverse and longitudinal waves.
Explanation
longitudinal waves: process reasoning for Transverse and longitudinal waves is correct because it uses the named objective and keeps the answer inside Transverse and longitudinal waves. It avoids confusing nearby wave boundaries such as amplitude versus wavelength, frequency versus period, or reflection versus refraction.
Common mistake
