Ray Diagrams - Lenses

Mr. Anderson explains how to draw ray diagrams for converging and diverging lenses, discussing vision issues like nearsightedness and farsightedness. He uses analogies to explain refraction and demonstrates how to determine the location of images using ray diagrams. The video also covers the differences between real and virtual images and suggests using simulations for better understanding.

What type of lens is used to correct nearsightedness?

• Converging lens

• Diverging lens

• Bifocal lens

• Cylindrical lens

What phenomenon occurs when light bends as it passes from one medium to another?

• Reflection

• Diffraction

• Refraction

• Dispersion

In a ray diagram for a converging lens, what happens to the rays when they pass through the focal point?

• They remain parallel

• They diverge

• They converge

• They reflect

What type of image is formed when rays converge on the opposite side of a converging lens?

• Real and upright

• Virtual and inverted

• Real and inverted

• Virtual and upright

When inside the focal point of a converging lens, what type of image is formed?

• Real and inverted

• Virtual and upright

• Real and upright

• Virtual and inverted

What is the characteristic of the image formed by a diverging lens?

• Real and upright

• Virtual and upright

• Real and inverted

• Virtual and inverted

As an object approaches the focal point of a diverging lens, what happens to the image?

• It disappears

• It becomes larger and inverts

• It becomes smaller and inverts

• It becomes larger and remains upright
