What is the de Broglie wavelength of the electron accelerated through a potential difference of ( 100 ) Volt?
Options
- A( 12.27 Å )
- B( 1.227 Å )
- C( 0.1227 ~A )
- D( 0.001227 0 A )
Correct answer
B. ( 1.227 Å )
Step-by-step solution
de Broglie wavelength of electron accelerated through a potential difference of ( V ) volt is given as [ = 12.27 V ] Here ( V=100 ) Volt Therefore, ( = 12.27 100 = 12.27 10 =1.227 AA )
