Parkinson's disease is a progressive nervous system disorder that can cause tremors in the hands and arms, rigid muscles and speech changes such as slurring, according to the Mayo Clinic. â
Electric power law: P = V x I   P = power in watts   Einstein's law: E â¦ = m x cÂ²   E = energy in joules, m = mass in kilograms, and c is the speed of light.
The Formula for Wavelength is given by the equation: $\lambda$ = $\frac{V}{f}$ where V = Speed of the wave, f = frequency of the wave. The above equation is also called as Wavelength Equation. From the above formula, we can find the Unit of Wavelength.
