Principal focus of a convex mirror is a virtual point. The parallel rays reflected form convex mirror only appear to come from the principal focus.

5. Focus of the Mirror: - The focus (F) of the mirror lies on the principal axis, at a distance equal to half of the radius of curvature (R) from the pole. Final Definition:The principal axis of a spherical mirror is the line that connects the center of curvature (C) to the pole...

These physical characteristics could permit ophthalmologists to “weld” a detached retina into place in a human eyeball by using the lens of the affected eye to focus the beam onto the retinal surface. If the single wavelength of the radiation from such a device happened to lie within the ...
Now, if you researched the district/school and found out what they are looking for in a candidate, you will be able to focus your response on that information, keeping in mind it is important to tell the truth. With every response you must show your VALUE to the district. This will ...

This feature is often used in metrology since the measurement error is reduced when compared to conventional lens systems because the centroid of the blur remains at the same height from the optical axis even as the focus is varied. Show moreView chapter Chapter The Oblique Aberrations Lens ...
