Good day, I need a little help understanding the following task. I'm really looking forward to your helpful answers. The two radii of curvature of a biconvex lens are increased by 20%. How does the refractive power of the lens change? What are the two radii of curvature here? I know what a biconvex lens…
Good day, I still need a little help to fully understand the topic. I'm looking forward to your helpful and detailed answers. Image construction The focal point is marked on both sides of the lens (the rays could also come from the other side). An axis is drawn through the focal points, which is called…
Good day, I still need a little help with this topic and am looking forward to your helpful and easy-to-understand answers. Diverging lenses also have a refractive power, but this is negative because the imaginary focal point and the focal length are in front of the lens and therefore have an opposite sign. I understand…
If I had a concave and convex air lens in the water, where would our parallel rays, focal rays, and center rays be? Or rather, what would happen?
An object and a screen are 100 cm apart, you want to create an image with a lens that you place between them, there is only one way to do this
Hi, Convex lenses (converging lenses) are spherical and thicker in the center than at the edges. They have the ability to convert diverging light into convergent light. In short, they deflect the beam toward the center of the lens. Concave lenses (diffusion lenses), on the other hand, have a flat shape and are thinner in…
