In Davisson and Germer experiment intensity of scattered beam of electron was maximum at

50^{\circ}

scattering angle and at

View answer and explanation

Correct option: C

54 \mathrm{~V}

accelerating potential

Option C (

54 \mathrm{~V}

accelerating potential) is correct because the maximum intensity of the scattered electron beam in the Davisson-Germer experiment occurs at approximately 54V.
