Why is there no refraction at 90 degrees?

Answers

Answered by ssasreeja

When the refraction of light occurs, the incident light rays bend. If the incident light ray is incident at 90°degrees, this means that it is parallel to the normal and it cannot bend away or towards it. ... If the light ray doesn't bend then refraction doesn't occur.
