How many rays of light do you need to draw to find where an image is located?
To determine the location of an image using ray diagrams, you need to draw two rays of light. One ray passes through the focal point before reflecting, and the other ray goes parallel to the principal axis and passes through the focal point after reflecting. The point where these two rays intersect will give you the location of the image.
How many light rays are required to locate the image formed by a lens?
2 is the minimum number of light rays required to locate the image (of a point object) formed by a lens. First find the path of rays after refraction and then their point of intersection gives the location of the image.
How to draw a ray diagram for a concave mirror?
To draw a ray diagram for a concave mirror, follow these steps: Draw the concave mirror as a curved line with a focal point (F) in the middle. Draw the object (usually an arrow) outside the mirror, beyond the focal point. Draw three rays: one parallel to the principal axis that reflects through the focal point, one through the focal point that reflects parallel to the principal axis, and one that goes through the center of curvature and reflects back on itself. Where the reflected rays intersect is where the image will form.
How do you draw a ray diagram for an object placed in front of a convex lens?
To draw a ray diagram for an object placed in front of a convex lens, first draw the principal axis and the lens. Then, draw three primary rays: one parallel to the principal axis that passes through the focal point on the other side of the lens, one passing through the center of the lens which continues straight, and one passing through the focal point on the same side of the lens which emerges parallel to the principal axis. The point where these three rays intersect will give the image location.
What happens when rays of light incident on a lens and parallel to the principal axis of the lens converge?
-- The distance from the center of the lens to the plane in which the rays converge is the 'focal length' of the lens. -- If the rays emanated from one point on an object, then rays from all the other points on the object do the same thing, and a real image is formed.
If the rays do not intersect at one point what do this indicate?
It means that they are skew.
What are two rays that intersect at more than one point?
no they can't
Can two rays intersect in more than one point?
no the definition is two lines intersecting once
Can three rays intersect at more than one point?
No. Ray= A finite beginning and no finite end. A ray is a linear projection in one direction. If three rays begin at the same point of origin they will never intersect again given their respective directions. Same goes for the situation of them beginning at different P.O.O's; it's only physically possible for them to intersect at one point then after. (Unless of course you bring into the picture mirrors and different mediums wherein the index could possibly cause them to reflect/refract and change their paths.. then they could possibly intersect at more than one point... BUT generally/simply speaking NO three rays cannot intersect at more than one point :-) )
Do two lines always intersect at one point?
If two different lines intersect, they will always intersect at one point.
When two lines intersect they intersect in one and only one?
Point.
Can three planes intersect in a point?
yes, three planes can intersect in one point.
Is it that if two different circles intersect then they intersect at one and only one point?
If two circles intersect then they have to intersect at two points.
When two lines intersect do they intersect in different ponts?
No, two straight lines can intersect at only one point and that is their point of intersection.
What are concurrent points?
A point of concurrency is a place where three or more, but at least three lines, rays, segments or planes intersect in one spot. If they do, then those lines are considered concurrent, or the the rays are considered concurrent.
I have to prove if two lines intersect then they intersect in no more than one point I have to assume that lines intersect in MORE than one point i have to prove tht they intersect MORE than 1 wrong?
wrong!
To cross at exactly one point?
To intersect.
