how to make projector working model school science project for exhibition

mobile-phone-projector-working-model-school-science-project-for-exhibition-diy-simple-and-easy-steps-diypandit

A simple mobile projector using a cardboard box, convex lens, and mobile phone works by utilizing the lens to focus light from the phone’s screen, projecting an enlarged image onto a surface. By adjusting the distance between the phone and the lens and ensuring a dark environment, this model effectively demonstrates basic principles of optics … Read more

how to make light refraction science working model experiment – using lens

light-refraction-science-working-model-experiment-using-lens

This experiment demonstrates the principle of refraction using a convex lens. A convex lens converges light rays passing through it, forming a real, inverted image on the opposite side. By adjusting the distances between the candle, lens, and screen, you can observe changes in the image, illustrating how lenses are used in various optical devices … Read more
