Question

what is the debroglie wavelength of an electron with a speed that is 5%of the light​

Answer 1

Answer:

$\huge\mathfrak\purple{Hey\ friend\ your\ answer\ is ...........}$

Given :

Speed of electron = 5% of light

$=> 3 × 10^8 × 5%$

$=> 3 × 10^8 × \frac{5}{100}$

$\underline{speed\ of\ electron = 15 × 10 ^6 m/s}$

Formula to be used :

$\boxed{\boxed{{\lambda} = \frac{h}{mv}}}$

Where ,

h = Plank's Constant

m = mass of particle

v = velocity of particle

$\huge{\frac {6625×10^ - 34}{2.18×10^6 × 15 × 10^6}}$
