Undergrad Resonant Frequency Formula for a given object

[btb4198]

I know the v = λf is the formula to find the resonance frequency of a single continuous wave and the formula for resonance frequency of a spring is: 1/2π∗sqrt(𝑘/𝑚)

but what about the Formula for a random object?
a car, or a rock, water ?

is there one Formula to rule them all? or do you have to develop an Formulae per object?
if so, how do you do that ?

Not really. That is the equation that relates the velocity of a traveling wave to its frequency and wavelength.

In general there will be many resonant frequencies of objects, and you will need to do computer simulations to try to figure out what they are.

One common way of calculating the resonant frequency of a simple geometry is to solve the Wave Equation:

Are you familiar yet with the Wave Equation?

I have hear of it before, but no I am not.
I use YouTube it and found these:

I will watch these videos on it
