Answer: hello your question is incomplete attached below is the complete question
answer : 1/2 KD^2 ( option A )
Explanation:
P.E ( potential energy ) = mgd
In case 1 P.E = 0 i.e. mgd = 0
Given that in case 2 the Mass M had moved through the Distance D by the compression of the spring
<u>The potential energy of the M in case 2 </u>
= P.E of M at rest + P.E of the spring
= 0 + 1/2 KD^2

Answer:
The distance is
Explanation:
From the question we are told that
The order of maximum diffraction is m = 2
The wavelength is
The angle is
Generally the condition for constructive interference for diffraction grating is mathematically represented as
where d is the distance between the lines on a diffraction grating
So
substituting values
