Wave length of light varies with color and due to variation of wavelength velocity varies .so different colors have different deviation
its called refraction
Index Of Refraction
Light whose wavelengths are the longest (eg red) undergo the greatest refraction.
why did you observe with indices of refraction of the colors of light in the acrylic prism
Reflection: light bounces off of a surface, like a mirror.Refraction: light goes through a substance and bends. For example, white light through a prism comes out in a rainbow because the light is refracted or bent and each color has a different index of refraction.
As it is parallel to the normal to the surface, the angle of incidence is zero and hence the angle of refraction also has to be zero. Hence no deviation and no refraction.
REFRACTION
Refraction is the bending of waves as they enter a different medium.
google the definition of refraction. thats how it bends.
refraction
spectrum is produced by the deviation of different colour by the means of refraction. When white light trevels from air into hollow prism (contains air) so there is no change of medium ,therefore no referaction and spectrum takes place.......
its called refraction
Refraction. White light is a mix of colors in the first place; these colors have different indices of refraction. That is, when moving from air to glass, as in a prism, they will bend at slightly different angles.
They both involve in like bending. There different because Refraction is the bending of a was as it enters a new medium and Diffraction is the bending of a was as it moves around an obstacle or passes through.
Waves change direction through refraction, and through reflection.
Water and air are different when it comes to light passing through them. This is called refraction.
There really is no similarity. One is that they are wave behaviors. Reflection is when a wave bounces off an object and comes back to you. Refraction is the bending of a wave through different materials because the substances are different. Mechanical waves travel faster in solids then liquids so refraction happens.
