Would the mirror equation work for plane mirrors?

No, it will not, this is because a plane mirror has no focal point. It's rays never converge at a single point like a concave mirror, and therefore it has no focal point The mirror equation is 1/f=1/di + 1/do, where f is the focal point, di is the distance of the image from the mirror, and do is the distance of the reflected object from the mirror. Since focal point is required for the equation, it can't work. Hope this helps.


What is the defition for plane flat mirror?

A plane flat mirror, as opposed to a concave or convex mirror, is flat and therefore has no focal point. Think of the mirror in your bathroom.


What is a focal length of a plane mirror?

Focaal length for plane mirror is 0


What is the power of a plane mirror?

Power is ZERO Since power = 1/ focal length As focal length of plane mirror is infinity, its reciprocal is 0


The distance between a mirror and its focal point is called the?

Focal length, positive number with a concave mirror, negative for a convex mirror.


What happens when a light ray passes through a focal point and then passes through a covex mirror?

Focal point of which mirror? Because convex mirror would have a virtual focus which is assumed to be at the back of the mirror.


Which term defines the distance from the focal point to either a lens or a mirror?

focal length


What is power of plane glass sheet?

it is zero . Power = 1/focal length The focal length of a plane glass or mirror is infinite, therfore power is zero


Which light rays striking a concave mirror are reflected so that they pass through they focal point?

Rays which are parallel to the axis of the concave mirror will converge to the focal point.


Are rays perpendicular to the principal axis of a concave mirror converge at or near the focal point?

It should be parallel. Rays "parallel to the principle axis of a concave mirror converage at or near the focal point.


The focal point of a concave mirror is 5 cm what is its center of curvature?

10 cm from the mirror.


What Is the focal point of a concave mirror?

It is the point at which light comes to a focus at a single point in space at a certain distance from the mirror relative to its curvature.
