Veins are blood vessels that carry deoxygenated blood back to the heart. They have thinner walls than arteries and often contain valves to prevent blood from flowing backward.
Lenses refract light, converging (convex) or diverging (concave) based on shape. They produce real or virtual images, affecting magnification and focus. Commonly used in cameras, eyeglasses, and microscopes.
A concave mirror curves inward and reflects light. It converges parallel rays to a focal point, enabling real or virtual image formation. Used in applications like makeup mirrors and telescopes.
Spherical lenses and mirrors have curved surfaces. Lenses can be converging (convex) or diverging (concave), affecting light focus. Mirrors, concave or convex, influence reflection properties, used in optics for various applications.
