I think you should just go for it and see where it takes you :)
If you don’t like it you can always change directions pookie
F=
(Natural frequency) (including fundamental)
n X F1
(Number of standing waves x fundamental frequency)
F( any Harmonic) =
(Frequency) ( no fundamental)
= vn/2L
(Speed of wave x n / 2x length of string)
Velocity =
(Waves
Frequency x wavelength
Wavelength of any standing wave (no fundamental)
2L /n
(2x length divided by number of standing waves)
Intensity =
Power/Area
(Surface area)
What is snells law
n1 x sin Θ1 = n2 x sin Θ2
What is the refractive index equation
n=c/v
(The absolute refractive index= speed of light in a vacuum divided by speed of light in material)
First harmonic =
Wave speed /2 x Length
Total energy transferred equation
W =
VIt
Energy transferr W=
Voltage(emf) x charge
Net Force =
Mass x acceleration
Acceleration =
Change in velocity / change in time
