If a proton were traveling the same speed as electrons in a tv picture tube (about 7.1 x 10^7 m/s), what would its de broglie wavelength be? the mass of a proton is 1.67 x 10^-27 kg. answer must be in m.

The wavelength is

Explanation:

Given that,

Speed

Mass of proton

We need to calculate the wavelength

Using formula of de Broglie wavelength

Put the value into the formula

Hence, The wavelength is
