IGCSE Grade 8 Science Reflection of coloured light
|
The angle of incidence does not directly affect the angle of total internal reflection
Dispersive reflection causes rainbows.
Reflection of red color
Surface composition
Shorter the wavelength, more is the chance of reflection
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.
The angle of refraction is the critical angle for total internal reflection.
The smoother the surface, more is reflection of light
When both of these angles are added together, they equal 90.
