It depends on two variables
v : speed of sound within this object
L : main lenght of this object
The natural frequency of the object will be v/L
Resonance
Resonance can occur when an object vibrates at another objects resonant frequency.
That depends on the type of siren. If you mean a Q then there is no set frequency.
Resonance can occur in any solid material where the frequency of oscillation in the material is equal to the natural frequency of the material.
Perhaps not much as the recessive allele is masked in heterozygous condition. Depends on penetration and expresivity of the lethal allele, but any homozygous expression is fatal, so one can expect negative frequency selection; the freqiency is kept low by selection.
Any object in absence of external force vibrates with it's natural frequency. When the frequency of the external forced vibration matches the object's natural frequency, we say that resonance has occurred. In this situation the amplitude of the object's oscillation becomes larger. How much larger depends on the amplitude of the forced vibration.

Resonance.
the result is resonance
Resonance - when pumping a swing in rhythm with its natural frequency, it produces larger amplitudes.(def. - occurs when the frequency of a vibration forced on an object matches the object's natural frequency and a dramatic increase in amplitude occurs)
The frequency or frequencies at which an object tends to vibrate with when hit or struck, plucked, strummed or somehow disturbed is known as the natural frequency.
Factors: elasticity and shape of the object
The frequencies of the harmonics are integer multiples of the natural frequency.
