How do you calculate frequency (by wavespeed x wavelength?)

Question

anonymous · Answer

$$f=v \div \lambda $$

anonymous · Answer

the lambda sign is the wavelength and the v is wvspd? Okay...and what is the wavespeed if the wavelength is 6 for example?

anonymous · Answer

what is frequency? you need to know wavelength and frequencies to solve for wave speed (velocity).

anonymous · Answer

Oh. F = cycles in given time . The way my science teacher did we didn't learn velocity .-.

anonymous · Answer

sorry for confusing velocity id wavelength. f is the number of cycles but what is the number of cycles?

is*

Example: A sound wave produced by a tuning fork travels with a speed of 342 m/s.  It has a frequency of 1600 Hz.
a)	What is the wavelength of the sound wave?

Solution: $$\lambda = v/f$$
$$\lambda = 342 / 1600$$
$$\lambda = 0.213 m $$
