364697 A plane mirror is reflecting a ray of incident light and is rotated through an angle of \(\theta \) about an axis which is perpendicular to the incident ray. If the plane mirror is perpendicular to incident ray initially, then

1 The reflected ray rotates through an angle of \(\theta \)
2 The reflected ray rotates through an angle of \(2\theta \)
3 The reflected ray does not rotate
4 None of these
