Exam-style question
Try this first
Which equation relates wave speed, frequency, and wavelength?.
- A.v = f × λ
- B.v = λ / f
- C.v = f / λ
- D.v = λ + f
Model answer
What a good answer should say
- v = f × λ
Explanation
Why this works
The wave speed equation states that wave speed (v) is equal to the frequency (f) multiplied by the wavelength (λ). This relationship is crucial for understanding how waves propagate.
