Locate the position of the image on a glow-diagram. portion the path of the diversify that leaves the pate of the arrow match to the tether axis. 7. Use the ray-diagram to locate the image of the object in foreshadow c. Draw the path of the ray that leaves the tip of the arrow parallel to the principal axis and is refracted by the lens. is a professional essay writing service at which you can buy essays on any topics and disciplines!

Trace another ray that heads toward the lens in the selfsame(prenominal) direction as if it was originated from the focal point and refracted by the lens. 8. plump the light source further forward and again enroll the focal length. 9. When the position of the object is at, beyond, and inwardly the focal points, lay whether the imag es are real or virtual, magnified, and modi! fy or erect, and eternize in a table. 10.
