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

The Correct Option is A, B

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) = \(\hat{y}\)
