Question #220449

What is the ratio of De Brogile's wave lengths of Mg^{2+} ion and C^{+} ion accelerated with 100 volts potentials each.

Expert's answer

"\\lambda=\\frac{h}{p}=\\frac{h}{\\sqrt{2mE}}\n\\frac{h}{\\sqrt{2mqV}}"

"\\lambda=\\frac{6.6\u00d710^{-34}}{\\sqrt{2\u00d79.1\u00d710^{-31}\u00d71.6\u00d710^{-19}\u00d7100}}"

"\\lambda=8.6\u00d710^{-11}"
