Question

The de -Broglie wavelength associated with an electron, accelerated through a potential difference of 100 volts is (A) 0.529nm (B) 52.9nm (C) 0.123nm (D) 1.23nm

Accelerating potential V=100V λ =(h/p)=(1 . 227/√V)nm λ =(1 . 227/√100)nm=0.123nm

Q. The $d e$ -Broglie wavelength associated with an electron, accelerated through a potential difference of $100$ volts is

$0.529 nm$

$52.9 nm$

$0.123 nm$

$1.23 nm$

Accelerating potential $V = 100 V$
$λ = \frac{h}{p} = \frac{1.227}{V} nm$
$λ = \frac{1.227}{100} nm = 0.123 nm$

0.529nm

52.9nm

0.123nm

1.23nm
