How do you make a ray diagram for converging lenses?
Pick a point on the top of the object and draw three incident rays traveling towards the lens. Using a straight edge, accurately draw one ray so that it passes exactly through the focal point on the way to the lens. Draw the second ray such that it travels exactly parallel to the principal axis.
How do you draw a ray diagram for converging and diverging lenses?
So for our first rule is that if we have an incident light ray traveling parallel to the principal axis. It’s going to start at the top of the balloon there travel parallel to the principal axis.
How do you draw a ray diagram for a diverging lens?
Step-by-Step Method for Drawing Ray Diagrams
- Pick a point on the top of the object and draw three incident rays traveling towards the lens.
- Once these incident rays strike the lens, refract them according to the three rules of refraction for double concave lenses.
- Locate and mark the image of the top of the object.
How do you draw ray diagrams?
This first ray though will be refracted. And to find the angle it’ll be refracted. At we need to draw a virtual ray between this point where it hits the lens. And the principal.
What are the rules of ray diagramming in lenses?
Rule 1: Incident light rays that are parallel to the principal axis will appear to come from the opposite focal point after refracting through the lens. Rule 2: Incident light rays that are directed at the optical center will pass directly through – in other words, they are not refracted.
How do you draw a ray diagram for a concave lens?
How to draw Concave Lens & Understanding ray Diagrams for …
What are the rules in ray diagramming?
Rules for drawing Ray Diagram in Lenses
- Rule 1 – Ray parallel to principal axis will pass through focus. For a convex lens ,
- Rule 2 – Ray passing through focus will become parallel to principal axis. For a convex lens,
- Rule 3 – Ray passing through Optical Center will emerge without deviation.

Case 2 – Object is between Infinity and Optical Center
| Position of the object | Position of the image | Nature of the image |
|---|---|---|
| At infinity | At focus F 1 | Virtual and erect |
| Between infinity and optical centre O of the lens | Between focus F 1 and optical centre O | Virtual and erect |

Why do we draw ray diagrams?
The goal of a ray diagram is to determine the location, size, orientation, and type of image that is formed by the concave mirror. Typically, this requires determining where the image of the upper and lower extreme of the object is located and then tracing the entire image.
What is an example of a converging lens?
Magnifying Glasses
The magnifying glass represents one of the simplest, most direct applications of a converging lens. As light enters the lens, it becomes focused to a specific focal point in front of the center of the lens.

What is F in ray diagram?
f = “focal length” = distance of F from lens.
How is image formed in converging lenses?
Positive, or converging, thin lenses unite incident light rays that are parallel to the optical axis and focus them at the focal plane to form a real image.
What is 2F in convex lens?
An object placed at 2F of a convex lens will produce an image at 2F. As you can clearly see in the diagram that the image formed is real and inverted.
What is a case 3 image?
Case 3: The object is located between 2F and F
Regardless of exactly where the object is located between 2F and F, the image will be located in the specified region. In this case, the image will be inverted (i.e., a right side up object results in an upside-down image).
What is the formula of mirror?
Let’s explore the mirror formula (1/f = 1/v+1/u) and see how to locate images without drawing any ray diagrams.
What is the formula of lens formula?
Let’s see how to use lens formula (1/v-1/u= 1/f) to locate images without having to draw ray diagrams.
