Which of the following is the correct ray diagram for a concave lens?
The ray diagram in option D is correct. After reflection, a ray of light incident parallel to the principal axis passes through the focus in case of a concave mirror.
How do you make a ray diagram for a concave 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 many ray diagrams does a concave lens have?
three principal rays
A ray diagram for a concave lens is composed of three principal rays: (1) Ray 1 – A ray is drawn parallel to the principal axis, where the refracted ray emerges from the focal point in front of the lens. (2) Ray 2 – A ray is directed toward the focal point in front of the lens.
What are the 3 rules for ray diagrams?
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.
Which of the following ray diagram is correct?
Which of the following uses concave lens?
Opticians use concave lenses to correct near-sightedness also called myopia.
How do you draw a ray diagram for lenses?
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 converging lenses.
- Mark the image of the top of the object.

Which image is formed by concave lens?
Concave lens always form virtual, erect and diminished image.
How many ray diagrams does a convex lens have?
There are basically three types of these lenses, they are the plano-convex lens, the double convex lens, and finally, concave-convex lens. We will now look at them in detail. Firstly, a plano-convex lens curves outwards from one side and the other side is plain.
What are the rules of concave lens?
Rules for obtaining images formed by concave lens
Rule 1: A ray of light parallel to the principal axis of the concave lens appears to be coming from focus after refraction through the lens. Rule 2: A ray of light passing through the optical centre of the concave lens goes straight after refraction through the lens.
What are the rules for drawing ray diagram for concave mirror?
rules for drawing images for concave mirror ray diagrams
- A ray of light running parallel to the principal axis passes through the principal focus F of a concave mirror after reflection.
- A ray of light passing through the centre of curvature in a concave mirror is reflected back along the same path.
Which of the following ray diagrams is correct for lens?
Explanation: The ray diagram in figure A is correct for the light ray incident on a lens as the incident ray travels through the focal point on the opposite side of the lens.
Which of the following ray diagram is not correct?
Option C is not correct. If the incident ray is parallel to the principal axis, then after reflection it should appear to pass through the focus.
What are 2 examples of a concave lens?
7 Concave Lens Examples in Daily Life
- Spectacles.
- Peepholes.
- Telescopes.
- Laser Devices.
- Cameras.
- Flash Lights.
- Binoculars.
What kind of image is formed by a concave lens?
upright, virtual
The images formed by the concave lens are always upright, virtual and smaller than the object.
How do you find the ray diagram?
How do you draw a concave and convex ray diagram?
Concave and Convex Mirror Ray Diagrams, Chapter 17 Review
How do you draw a ray diagram lens?
What are the examples of concave lens?
Some examples include:
- Binoculars and telescopes.
- Eye Glasses to correct nearsightedness.
- Cameras.
- Flashlights.
- Lasers (CD, DVD players for example).
What do concave lenses form?
Concave lens forms virtual,upright and diminished image for all positions of the object.
What is the shape of concave lens?
A concave lens is also known as a diverging lens because it is shaped round inwards at the centre and bulges outwards through the edges, making the light diverge. They are used to treat myopia as they make faraway objects look smaller than they are.
What are the types of concave lens?
Types of concave lens : Biconcave lens, plano-concave lens, convexo-concave lens.
What image is formed in concave lens?
virtual images
Concave lenses create only virtual images. After the rays are refracted, they never converge and so there will be no real images. All concave lens images will be upright, virtual, and diminished, and can be found between the F and the lens.
What are the 4 rules of concave mirror?
Rules for Obtaining Images Formed by a Concave Mirror
- A ray coming parallel to the principal axis is reflected through the principal focus of the concave mirror.
- The ray of light passing the principal focus becomes parallel to the principal axis after being reflected from the mirror.
