If light, travels from one medium to
another in which case the change in speed will
be o lil minimom (i Maximum.​

Answer 1

Answer:

Explanation:

When light travels from vacuum to a medium of refractive index ‘n’ then it’s speed changes from c to c/n. So the speed will be minimum at medium D and Maximum at medium A

speed of light will be slower in,, the medium having higher refractive indexes,,, where as speed of light increases when it goes to medium of lower refractive indexes. in this case speed of light will be highest in medium a.. where Ajit will be slower in medium d.. highest refractive index

In case the speed of light is great maximum, it means that the refractive index would be quite less.

• If the speed of light is lower minimum, it indicates that the refractive index would be on the greater side.

• One of the most important aspects of the phenomenon is that both physical quantities are inversely proportional to each other.

The cause of refraction is a change in light speed; and wherever the light speed changes most, the refraction is greatest. The speed is related to the optical density of a material that is related to the index of refraction of a material. Air is the least dense material (lowest index of refraction value) and water is the denser material (largest index of refraction value). Thus, it would be reasonable that the most refraction occurs for the transmission of light across an air-water boundary.

Refractive index is the the ratio of the velocity of light in a vacuum to its velocity in a specified medium.

Here, the refractive index will be more for a more denser medium as the speed of light through a denser medium will be lesser.

Hence, the speed of light is maximum in the B.
