IGCSE Grade 8 Science Reflection of coloured light
|
Surface composition
Rather than scattering at just one angle, ray incident on the surface is scattered at many angles
The refractive index of a medium is a measure of how much light slows down or bends as it passes through that medium compared to the speed of light in a vacuum.
Reflection of red color
When both of these angles are added together, they equal 90.
The angle of incidence directly affects the amount or intensity of light that is reflected from a surface..
The angle of incidence does not directly affect the angle of total internal reflection
Angle of reflection = angle of incidence
The smoother the surface, more is reflection of light
The angle of refraction is the critical angle for total internal reflection.
