Strictly speaking, if you know certain properties of a wave, you can calculate its frequency, but usually a mechanism or a source of energy is what "determines" ("causes") a frequency. (Sorry to nit pick - I think I know what you're asking.)
The equation v = f*λ is true of all mechanical waves where v is the speed of wave propagation (that is, how fast a typical "crest," moves through space), f is the frequency (the number of complete cycles which occur in one second) and λ is the wavelength (how long, spatially, a complete wave cycle is).
Often you won't have access to these properties directly, but perhaps you are given the distance the wave travels in a certain time period (distance/time = average velocity = v) or the length of half a wavelength ( = 1/2 λ) or the period of the wave (defined as 1/f, a measure of the length of time for one cycle to occur).

What determines the frequency of an electromagnetic wave?
The frequency of the source that produced the wave.
Which feature of a sound wave determines the pitch of the sound?
That's the wave's frequency.
What determines the energy of an electromagnetic wave?
Frequency determines the scalar energy of electromagnetic wave, E= hf=hc/r.
The distance between successive crests or troughs determines wave?
Wave length.
What determines the color of a electromagnetic light wave?
Its wavelength/frequency.
What determines a wavelength of a wave?
The frequency
What determines the frequency of an electromagnetic wave?
The frequency of the source that produced the wave.
What wave property determines pitch?
The frequency.
What wave property determines loudness and pitch?
The wave's frequency and its amplitude.
The frequency of a sound wave determines?
the pitch of the sound.
Which feature of a sound wave determines the pitch of the sound?
That's the wave's frequency.
What determines the energy of an electromagnetic wave?
Frequency determines the scalar energy of electromagnetic wave, E= hf=hc/r.
Which characteristic of sound is associated with frequency?
We perceive the loudness of a sound wave as a consequence of its amplitude. The frequency of a sound wave determines the pitch we perceive.
The distance between successive crests or troughs determines wave?
Wave length.
What determines the frequency of the wave?
The number of cycles in a given time. :)
