Description
Refraction of Light
When light passes through a transparent material like glass, it often bends and comes out in a slightly different place. This is called refraction.
For example, your spectacles that help with reading or seeing far-off objects work on this principle.
Refraction is also commonly seen in prisms. You can see light splitting and emerge out in its basic colours, Violet, Indigo, Blue, Green, Yellow, Orange and Red (VIBGYOR).
The most common occurrence of refraction in nature you must have seen is the appearance of a rainbow after during or after rain; especially when sunlight is also visible during the rain. Sunlight passes through tiny water droplets in the atmosphere. The tiny water droplets appear as one giant prism and when light passes through them, a rainbow is formed.
Curved Mirror
A curved mirror is a mirror with a curved reflecting surface. The surface may be either convex or concave. Most curved mirrors have surfaces that are shaped like part of a sphere, but other shapes are sometimes used in optical devices.

What are Lenses
A transparent material bound by two surfaces, of which one or both surfaces are spherical, forms a lens. The two types of lenses are:
Convex lens or converging lens converges light rays.
Concave lens or diverging lens diverges light rays.
Important Terms
Centre of Curvature | Principal Axis | Optical Centre | Aperture | Focal Length
Spectrum
A spectrum is a condition that is not limited to a specific set of values but can vary, without steps, across a continuum. The word was first used scientifically in optics to describe the rainbow of colors in visible light after passing through a prism.
