# Question: A proton traveling at a speed of 4 5 x 104

A proton traveling at a speed of 4.5 x 104 m/s is accelerated through a potential difference of 37 V.

(a) Will its de Broglie wavelength (1) increase, (2) remain the same, or (3) decrease, due to the potential difference? Why?

(b) By what percentage does the de Broglie wave-length of the proton change?
