Question

an object is 6 cm in front of a converging lens with a focal length of 10cm. draw a ray diagram (to scale with a ruler) to find the location of the image. is the image upright or inverted, and is the image real or virtual?

Answer 1

To draw a ray diagram for a converging lens, follow the steps: draw principal axis, mark focal points, trace incident rays, determine intersection point of rays, and identify image characteristics. The image formed will be virtual, upright, and larger than the object.

Step-by-step explanation:

To draw a ray diagram, we need to follow certain rules:

1. Draw the principal axis of the lens, which is a straight line passing through the center of the lens.
2. Mark the focal point on both sides of the lens. For a converging lens, the focal point is on the opposite side of the incoming light.
3. Take an incident ray from the top of the object and draw it parallel to the principal axis. Then, pass it through the focal point on the opposite side.
4. Take another incident ray from the top of the object and pass it through the center of the lens.
5. Where the two rays intersect after refraction, that point represents the top of the image. Repeat the same steps for the bottom of the object to determine the bottom of the image.
6. The image formed by a converging lens when the object is closer than the focal point is virtual, upright, and magnified.

Based on the given information, the image will be virtual, upright, and larger than the object. The location of the image will be on the same side as the object, and it will be farther away from the lens than the object.
