Conditions :

• If the refractive indices are same in both medias then there will be no refraction and light will pa:ss without any refraction

Answer 2

Refraction :- It is the bending of a light ray due to the decrease in its speed .

in case , there is no object or medium in b/w of light Rays there would be no bending of light and thus , there would be no refraction .

Explanation:

it simply means that when light ray went or passes in straight line there would be no any refraction .
