The top color in the rainbow is while the color is becauseExplanation / Answer
1. Reflection and refraction is described as being both electromagnetic and mechanical waves.
2. Critical angle is minimum angle when a ray goes from densor to rare medium that mininum incident angle at refraction angle is 90 degree than its angle is called critical angle.
3. When light goes from densor to rare medium if it reflect in densor medium than this incident called total internal reflection
4. n1 is higher refractive index than n2
