Find the debroglie wavelength of an electron with 4.0 ev.

Explanation:

It is given that,

Voltage,

De broglie wavelength in terms of voltage is given by :

m and e are the mass and charge on electron. So,

So, the De broglie wavelength of an electron is 1.53 meters. Hence, this is the required solution.      

there is no correct list among the choices you've provided.

the list might look something like this:

-- baby human

-- piccolo

-- flute

-- soprano singer

-- trumpet

-- tenor singer

-- trombone

-- baritone singer

-- baritone horn

-- bass singer

-- tuba

since i had to make up the list myself, i made it easy on myself, and i didn't try to shuffle the string instruments and woodwinds into it too.
