拜託大大請幫我翻譯(只要翻譯就好,不用計算)
這是出自物理的某本書,請大大幫我翻譯成中文,不用計算,謝了:
1.Find the de Broglie wavelength of a 1.0-mg grain of sand blown by the wind at a speed of 20 m/s.
2.Find the de Broglie wavelength of a 1.00-MeV proton. Is a relativistic calculation needed?
3.Green light has a wavelength of about 550 nm. Through what potential difference must an electron be accelerated to have this wavelength?
4.A proton in a one-dimensional box has an energy of 400 keV in its first excited state. How wide is the box?

1.Find the de Broglie wavelength of a 1.0-mg grain of sand blown by the wind at a speed of 20 m/s.
找出因風吹而有20m/s速度的1.0-mg沙粒之德布洛依波長。
2.Find the de Broglie wavelength of a 1.00-MeV proton. Is a relativistic calculation needed?
計算1.00-MeV質子之德布洛依波長。
本題需要相對論計算嗎?
3.Green light has a wavelength of about 550 nm. Through what potential difference must an electron be accelerated to have this wavelength?
綠光波長約為550 nm。
要有多少位能差才能使一個電子加速至具備該波長?
4.A proton in a one-dimensional box has an energy of 400 keV in its first excited state. How wide is the box?
在一維空間盒子裡,有個在第一激發態的質子具400 keV能量。
盒子多寬?
