The ball should take twice as long to return to its original position as it took to reach its maximum height, so it should return to its original position at .
Answer:
0.541 nm
Explanation:
The condition for maxima is,
Here, m=0,1,2,.....
And d is the slit separation, m is the order of maxima, is the wavelength.
Given that, the 17.3 eV electron posses a wavelength of
And the order of maxima is .
And the angle at which first order maxima occur is, .
Put these values in maxima condition while solving for d.
Therefore, the slit separation is 0.541 nm.
