... refraction states that when a light ray strikes a reflecting surface, the angle of reflection is equal to the angle of incidence. The angle of incidence and the angle of reflection are measured from a normal that is perpendicular to the angle of incidence. Reflected rays are scattered in different directions depending on the surface reflected on. A diffuse reflection is a reflection of light into many directions by ... of incidence, 0r= angle of reflection, and n= the index of refraction of the medium. The final section of the chapter is on the index of refraction and speed of light. Th...

... colours, the colours of the rainbow. When light is passed through the two sides of a raindrop, it can be made to bend. The seven light frequencies are bent at different angles and are separated out. When the light is bending like this, it is called refraction. The different colours of the light spread out because of this refraction. The red light is bent the least and violet ... light the most, that's why the arch of the red light is the largest and the violet is the smallest. If you want to see a rainbow ... angle from the antisolar point. If you are standing outside during the daytim...
