- i *wavelength*, λ
- ii *frequency*, f
- iii *time period*, T
- iv *amplitude*, A
- v *wave speed*, v
2. (b) How are frequency and time period related mathematically?
3. (c) On which of the properties listed in part a does the energy being transferred by a wave depend?
4. (d) Explain what is meant by the term *mechanical wave*.
