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.
Answers:The standard formula for the relationship between wavelength and frequency is: (wavelength) = c (speed of light) / v (frequency) (With this problem, you don't need Planck's constant (6.626 * 10^(-34)), that's only used when measuring energy a certain wavelength or frequency puts out.
