identify the situation where the light ray does not change the direction during the refraction
Answers
Answer:
The only time that a wave can be transmitted across a boundary, change its speed, and still not refract is when the light wave approaches the boundary in a direction that is perpendicular to it. As long as the light wave changes speed and approaches the boundary at an angle, refraction is observed.

I hope it will helpful to you and thankful to me plzzzz
Answer:
Angle of the incident ray
Explanation:
If the light is entering the substance at a greater angle , the amount of refraction also be more noticeable.On the other hand , if the light is entering the new substance from straight on (at 90° to the surface), the light will still slow down, but it won't Change the direction at all..........
