Question: Q. 2. Consider the given figure. Suppose the voltage applied to
(a) will be larger than the earlier value.
(b) will be the same as the earlier value.
(c) will be less than the earlier value.
(d) will depend on the target.
Show Answer
Solution:
Ans. Correct option : (c)
[NCERT Exemplar] Explanation :
In Davisson-Germer experiment, the de-Broglie wavelength of diffracted beam of electrons
From equation (i), as the applied voltage in this experiment increases, the wave length
