Convex mirrors are used in automobiles to see the rear side traffic. They provide a wider field of view compared to plane mirrors, allowing drivers to see more area behind them. The convex shape makes objects appear smaller but covers ...

When a convex lens is immersed in water, its focal length decreases. This is because the refractive index of water is higher than that of air, causing light to bend more sharply, effectively decreasing the lens’s ability to converge light ...
The unit of the power of the lens is diopter. It measures the refractive power of a lens, indicating how strongly the lens converges or diverges light. It is defined as the reciprocal of the focal length in meters.
When a ray of light travels from a rarer medium to a denser medium, it gets bent towards the normal. This bending occurs because the light slows down in the denser medium, causing the direction of the ray to shift ...
A spherical air bubble embedded in glass behaves optically like a converging lens. Due to the curvature of the bubble’s surfaces, it causes light rays passing through it to converge, similar to how a convex lens bends light towards a ...
