identify the conditions under which refraction of light occurs
- Light rays travel in straight lines. However, if a light ray passes from one medium to another at an angle other than 90 ยบ, the ray is bent. This bending, as light passes from one medium to another, is called refraction.
- Refraction of light occurs when light passes from one substance to another.
