364719 To produce a parallel beam from a spherical concave mirror a point source should be placed at

1 Centre of curvature
2 Focus
3 Infinite distance
4 Pole
PHXII09:RAY OPTICS AND OPTICAL INSTRUMENTS

364720 Assertion :
The mirror formula related with \(u,{\rm{ }}v\) and \(f\) for spherical mirror is valid only for mirrors whose sizes are very small compared to their radii of curvature.
Reason :
Laws of reflection are strictly valid for plane surfaces, but not for large spherical surface.

1 Both Assertion and Reason are true and Reason is correct explanation of the Assertion.
2 Both Assertion and Reason are true but Reason is not the correct explanation of the Assertion.
3 Assertion is true but Reason is false.
4 Assertion is false but Reason is true.
PHXII09:RAY OPTICS AND OPTICAL INSTRUMENTS

364721 Assertion :
The edges of the images of white object formed by a concave mirror on the screen appear white.
Reason :
Concave mirror does not suffer from chromatic aberration.
