Answer :
In accordance with the law of refraction, when a ray transitions into a material with a higher refractive index, it will undergo bending towards the normal. Hence, the first option aligns well with the answer.
Refraction is the bending of light as it passes from one medium to another, such as from air to water or from air to glass. The refractive index is a measure of how much the speed of light is reduced in a particular material compared to its speed in a vacuum.
When a ray of light passes from a medium with a lower refractive index to a medium with a higher refractive index, such as from air to glass, it slows down. This causes the light ray to bend towards the normal, which is an imaginary line perpendicular to the surface of the medium at the point of incidence. The extent of the bending is determined by the refractive indices of the respective materials involved in the refraction process.
To understand this concept, let's consider an example. Imagine you have a swimming pool with a clear glass wall. When you look at an object underwater from outside the pool, the object appears to be displaced or shifted towards the normal. This is because the light rays coming from the object in water bend towards the normal as they enter the air, resulting in the apparent shift.
In summary, when a ray of light enters a material with a higher refractive index, it will bend towards the normal. This is a fundamental principle known as the law of refraction.
The question should be:
According to the law of refraction, a ray entering a material with higher refractive index will: bend towards the normal. bersd far from the normal. continue straight without being deviated bend with an anle of 180º
