Answer:
Part a)
Width of the slit is
Part b)
Ratio of intensity is given as
Explanation:
Part a)
As we know by the formula of diffraction we will have
so we have
so we will have
Part b)
As we know that the intensity in diffraction pattern is given as
so for angle 45 degree
Given:
Work done, W = 5 J
Initial energy = 8J
Final energy = 30J
Let's determine if the work done have a positive or nrgative value.
Appy the equation for the first lae of thermodynamics:
Where:
U is the change in internal energy
Q is the added heat
W is the work done
To find the work done here, we have:
Rewrite the formula for W
Where:
ΔU = 30J - 8J = 22J
Q = 5J
Thus, we have:
Therefore, the work done here is -17J.
This means the work done in this scenario has a negative value.
ANSWER:
The work done in this scenario has a negative value
