A bug is placed 10.0 cm in front of a lens. The lens forms an image on a white screen 30.0 cm behind the lens. Draw a ray diagram to show the formation of the image.
A bolt lies 6.0 cm on the front side of a converging lens and has a focal length of 4.0 cm. Use a ray diagram to find the location of the bolt's image. State if the image produced will be upright or upside down.
A concave lens of focal length - 8 cm is used to form the image of a 2.0 cm high object located 10 cm in front of the lens. Use graph paper and ray tracing techniques to locate the image. Measure the image position and height from your diagram.
