Question

A linearly polarized light beam travels from origin to point A (1,0,0). At the point A, the light is reflected by a mirror towards point B (1, -1,0). A second mirror located at point B then reflects the light towards point C (1,-1,1). Let n(x, y, z) represent the direction of polarization of light at (x, y, z).

• A. If $\hat{n}$(0, 0, 0) = $\hat{y}$, then $\hat{n}$(1, -1, 1) = $\hat{x}$
• B. If $\hat{n}$(0, 0, 0) = $\hat{z}$, then $\hat{n}$(1, -1, 1) = $\hat{y}$
• C. If $\hat{n}$(0, 0, 0) = $\hat{y}$, then $\hat{n}$(1, -1, 1) = $\hat{y}$
• D. If $\hat{n}$(0, 0, 0) = $\hat{z}$, then $\hat{n}$(1, -1, 1) = $\hat{x}$

Answer 1

Answer: (A), (B)

If $\hat{n}$(0, 0, 0) = $\hat{y}$, then $\hat{n}$(1, -1, 1) = $\hat{x}$

Answer 2

The correct option is (A): If $\hat{n}$(0, 0, 0) = $\hat{y}$, then $\hat{n}$(1, -1, 1) = $\hat{x}$ and (B): If $\hat{n}$(0, 0, 0) = $\hat{z}$, then $\hat{n}$(1, -1, 1) = $\hat{y}$
