when incident is prependicular to the plane of separation then angle of incident is equal to the sin i=0sin0=0so we get refractive index zero/
When light passes through the center of a lens, it travels along the optical axis, where the lens is thinnest. Since this is the region with the least curvature, the light does not bend much as it passes through. The amount of bending depends on the angle at which the light enters the lens, with light entering perpendicularly experiencing minimal bending.
If more electric field lines are leaving a Gaussian surface than entering, this indicates that there is a net positive charge enclosed by the surface. According to Gauss's Law, the total electric flux through a closed surface is directly proportional to the net charge enclosed by that surface.
When the magnetic flux through a closed surface is zero, it means that the magnetic field lines entering the surface equal the field lines leaving it. This can occur when the surface encloses no magnetic sources or when it lies parallel to the magnetic field lines. Mathematically, it can be expressed as ∮B⋅dA = 0, where B is the magnetic field and dA is the differential area vector.
Light passes through water by entering the water, slowing down, bending due to the change in optical density, and continuing to travel through the water until it reaches the surface or an object that absorbs or reflects the light.
The light will pass straight through the glass block if shone perpendicularly, without getting refracted or bent due to the change in medium.
The materials entering or leaving a cell need to pass through the cell surface.

Most of the water entering the plant through the roots is absorbed by the root hairs, which are tiny extensions on the root surface that greatly increase the root's surface area for absorption. This water is then transported up through the xylem tissue in the stems to reach the rest of the plant for various physiological processes.

The fibre of the mask traps dust and paint molecules. Air can get through, as air molecules are very much smaller, passing through the minute holes in the fibre.
The greatest source of moisture entering the atmosphere is evaporation from the oceans. Oceans cover about 71% of the Earth's surface and release a significant amount of water vapor into the atmosphere through evaporation. This water vapor plays a key role in the water cycle and influences global weather patterns.
