Where Do The Three Rays In A Ray Diagram Start

There are three principal rays. In a 3 step process use three principal rays to draw a ray diagram.

1 Concave Lens Main Three Rays And Ray Diagram Youtube

Step by step method for drawing ray diagrams.

Where do the three rays in a ray diagram start. A ray parallel to the axis ray 1 diverges along a line through the near focal point. A ray through the center of the lens ray 3 does not bend. A ray diagram for the case in which the object is located in front of the focal point is shown in the diagram at the right.

Ray diagram for the formation of a virtual image. A rays through the center of the lens that does not change direction. A ray parallel to the axis ray 1 diverges along a line through the near focal point.

Three easy rays axis cleo stated that light travels through air in straight paths and when it moves from air to water light changes direction speeds up and bends toward the normal. It is usually best to place the base of the arrow on the axis and to draw the arrow about half the radius of the lens. At a focal point on the opposite side of the lens at three different points on the object at a focal point on the same side of the lens at a single point on the object.

A ray along a line toward the far focal point ray 2 emerges parallel to the axis. Observe that in this case the light rays diverge after reflecting off the mirror. Draw the rays from the tip of the object to the lens plane.

The image point of the top of the object is the point where the three refracted rays intersect. Trace the diverging rays backward. A ray parallel to the principal axis that passes through the focal point after refraction by the lens.

Draw a ray starting from the top of the object parallel to the principal axis and then through f after reflection. The second principal ray occurs when light comes in through the focus then it comes out parallel to the principle axis. Draw the three special rays from the tip of the arrow.

Since the three refracted rays are diverging they must be extended behind the lens in order to intersect. All lenses and mirrors can use ray diagrams to find images. Where do the three rays in a ray diagram start.

A ray through the focal point in front of the lens that emerges parallel to the principal axis after refraction by the lens. The first principal ray occurs when the light comes in parallel to the principle axis it goes out through the focus. Using a straight edge extend each of the rays using dashed lines.
