Answer to Problem 4.65P
Constructed the quadruplet and the two doublets using the notation of Equation 4.175 and 4.176:
The quadruplet is,
The doublet 1 is
The doublet 2 is
Explanation of Solution
To construct the quadruplet:
Let
Write the expression for lowering operator for one particle, Equation 4.146
And,
For all three states,
Therefore, the other states of the lowering operator is
From above equations,
Solving to find
Solving to find
Solving further,
Thus, the quadruplet is
To construct doublet 1:
Let
Hence,
Thus, the doublet 1 is
To construct doublet 2:
Let
Since,
Similarly to find
Since,
For normalization,
Substituting the relation of
The,
Substituting the value of
To solve for
Therefore,
Thus, the doublet 2 is

- How can i solve this if n1 (refractive index of gas) and n2 (refractive index of plastic) is not known. And the brewsters angle isn't knownarrow_forward2. Consider the situation described in problem 1 where light emerges horizontally from ground level. Take k = 0.0020 m' and no = 1.0001 and find at which horizontal distance, x, the ray reaches a height of y = 1.5 m.arrow_forward2-3. Consider the situation of the reflection of a pulse at the interface of two string described in the previous problem. In addition to the net disturbances being equal at the junction, the slope of the net disturbances must also be equal at the junction at all times. Given that p1 = 4.0 g/m, H2 = 9.0 g/m and Aj = 0.50 cm find 2. A, (Answer: -0.10 cm) and 3. Ay. (Answer: 0.40 cm)please I need to show all work step by step problems 2 and 3arrow_forward
- look at answer show all work step by steparrow_forwardLook at the answer and please show all work step by steparrow_forward3. As a woman, who's eyes are h = 1.5 m above the ground, looks down the road sees a tree with height H = 9.0 m. Below the tree is what appears to be a reflection of the tree. The observation of this apparent reflection gives the illusion of water on the roadway. This effect is commonly called a mirage. Use the results of questions 1 and 2 and the principle of ray reversibility to analyze the diagram below. Assume that light leaving the top of the tree bends toward the horizontal until it just grazes ground level. After that, the ray bends upward eventually reaching the woman's eyes. The woman interprets this incoming light as if it came from an image of the tree. Determine the size, H', of the image. (Answer 8.8 m) please show all work step by steparrow_forward
