Which of the following is the best example of refraction of a light wave?

Glass. Glass is a perfect everyday example of light refraction. Looking through a glass jar will make an object look smaller and slightly lifted. If a slab of glass is placed over a document or piece of paper, then the words will look closer to the surface because of the different angle the light is bending.

Why does light take the least time path?

Physicist: Light travels at different speeds in different materials. When you shine a beam of light from one material into another (like from air to water) it bends in such a way that the path it takes from one point to another requires the least possible time.

What is the principle that describes how light travels the path that requires the shortest amount of time?

Fermat’s principle
Fermat’s principle states that “light travels between two points along the path that requires the least time, as compared to other nearby paths.” From Fermat’s principle, one can derive (a) the law of reflection [the angle of incidence is equal to the angle of reflection] and (b) the law of refraction [Snell’s law].

When light gets reflected from a surface it selects the path that takes the least possible time this principle was given by?

Pierre de Fermat
Pierre de Fermat (1601−1665) showed that whenever light travels from one point to another, its actual path is the path that requires the smallest time interval. This statement is known as Fermat’s principle.

What is light refraction example?

What are some examples of refraction of light? “The process of bending of light as it passes from air into glass and vice versa is called refraction of light.”Mirage,bent pencil in glass of water,rainbow,sunset are some examples of refraction of light.

What is refraction of light give example?

Refraction is the bending of a light or sound wave, or the way the light bends when entering the eye to form an image on the retina. An example of refraction is a bending of the sun’s rays as they enter raindrops, forming a rainbow.

What path does light take?

Whether it is traveling through air, water, glass, diamond, a smoky Broadway stage, or any other transparent substance (or in nothing — the vacuum of space), light travels in a straight path until it encounters a different medium. So straight that analogies fail — the path of light is the Ultimate Straight Line.

Why does light always take the quickest path?

Answer: Since light is always in a hurry, it bends when it enters a different medium as it is still following the quickest path. This phenomenon of light bending in a different medium is called refraction.

Who said that light select the path which takes the least time to travel?

Fermat’s principle, also known as the principle of least time, is the link between ray optics and wave optics. In its original “strong” form, Fermat’s principle states that the path taken by a ray between two given points is the path that can be traveled in the least time.

When a light ray reflects from the boundary surface the following will change?

Explanation: When light reflects from a boundary surface then there is no change in frequency.
