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.

The formation of a rainbow is due to the refraction, dispersion, and reflection of sunlight by water droplets in the atmosphere. Sunlight entering the droplets is refracted, split into its component colors, internally reflected, and then refracted again as it ...
Total internal reflection occurs when light travels from a denser medium to a rarer medium, with an angle of incidence greater than the critical angle. This phenomenon causes the light to be completely reflected back into the denser medium, rather ...
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 stick immersed in water appears bent due to the refraction of light. When light travels from water to air, it bends at the interface. This bending alters the apparent position of the stick, making it look bent at the ...
