The angle of deviation for the first prism P1
δ1 = (µ1 – 1) A1
The angle of deviation for the second prism P2
δ2 = (µ2 – 1) A2
Since total deviation is to be zero
∴ δ1 + δ2 = 0

However, I can explain the concept and steps to solve the problem.
To solve this problem, we can use the formula for the deviation angle of a prism:
Deviation angle = (n-1) x A
where n is the refractive index of the prism material and A is the angle of the prism.
In this case, the thin prism P1 has an angle of 4° and the refractive index of the material is not given. So, we cannot calculate the deviation angle directly.
However, we are given that the prism P1 produces a deviation of 4° when a parallel beam of light passes through it. This means that the prism is producing minimum deviation, which occurs when the angle of incidence and angle of emergence are equal.
Using this information, we can apply the formula for minimum deviation angle of a prism:
Minimum deviation angle = (A/2) x (n-1)
where A is the angle of the prism.
Substituting the values given, we get:
4° = (4/2) x (n-1)
Simplifying this equation, we get:
2n - 2 = 4/4
2n - 2 = 1
2n = 3
n = 3/2
Therefore, the refractive index of the prism material is 3/2.
Now, we can use the formula for deviation angle to calculate the angle of incidence for the second prism P2:
Deviation angle = (n-1) x A
20° = (3/2 - 1) x A
20° = (1/2) x A
A = 40°
Therefore, the angle of incidence for the second prism P2 is 40°.
To solve this problem, we can use the formula for the deviation angle of a prism:
Deviation angle = (n-1) x A
where n is the refractive index of the prism material and A is the angle of the prism.
In this case, the thin prism P1 has an angle of 4° and the refractive index of the material is not given. So, we cannot calculate the deviation angle directly.
However, we are given that the prism P1 produces a deviation of 4° when a parallel beam of light passes through it. This means that the prism is producing minimum deviation, which occurs when the angle of incidence and angle of emergence are equal.

2n - 2 = 4/4
2n - 2 = 1
2n = 3
n = 3/2
Therefore, the refractive index of the prism material is 3/2.
Now, we can use the formula for deviation angle to calculate the angle of incidence for the second prism P2:
Deviation angle = (n-1) x A
20° = (3/2 - 1) x A
20° = (1/2) x A
A = 40°
Therefore, the angle of incidence for the second prism P2 is 40°.
