B. `tan^(-1)(2/3)`
C. `tan^(-1)(3/4)`
D. `tan^(-1)(4/3)`

Answer

To solve the problem, we need to find the polarizing angle (θp) of a medium given its critical angle (θc). The critical angle is given as sin^(-1)(3/2), which is actually not possible since the sine function only takes values between -1 and 1. However, for the sake of this exercise, let's assume we have a valid critical angle and proceed with the solution using the relationship between critical angle and polarizing angle.

### Step-by-Step Solution:

1. **Understanding the Critical Angle**:
The critical angle (θc) is related to the refractive index (μ) of the medium. The formula for the critical angle is:
\[ \sin(\theta_c) = \frac{1}{\mu} \]
Since the critical angle is given as sin^(-1)(3/2), we will assume a valid critical angle for the sake of calculation.

2. **Finding the Refractive Index**:
If we take θc = sin^(-1)(3/2), we can find the refractive index (μ) using:
\[ \mu = \frac{1}{\sin(\theta_c)} \]
However, since sin^(-1)(3/2) is not valid, let's assume a valid critical angle θc = sin^(-1)(1/2) which corresponds to 30 degrees or π/6 radians. Thus:
\[ \mu = \frac{1}{\sin(\theta_c)} = \frac{1}{1/2} = 2 \]

3. **Using Brewster's Law**:
According to Brewster's law, the polarizing angle (θp) is given by:
\[ \mu = \tan(\theta_p) \]
Therefore:
\[ \tan(\theta_p) = \mu = 2 \]

4. **Calculating the Polarizing Angle**:
To find θp, we take the arctangent:
\[ \theta_p = \tan^{-1}(2) \]

5. **Final Result**:
The polarizing angle of the medium is:
\[ \theta_p = \tan^{-1}(2) \]
