Dispersion of Light

• Dispersion of light refers to the spreading of light into its color components
• The different colours in visible light spectrum will form a white light
• Refraction is the bending of light is affected by the material's Index of refraction
• The boundary between two materials where light passes through is called normal line
• Dispersion of light is the index of refraction of any material is dependent on the wavelength of light
• As the wavelength of the light increases, the index of refraction of the material decreases
• Refracted ray that leaves the prism will be diverged from its original diviation refered to as the angle of deviation
• Rays corresponding to different colours are bent by the prism in varying amounts (angle)
• Rainbow are formed by the dispersion of light in water droplets
• Arc that subtends an angle of 42 for red light and 40 for violet light
• The spreading of light into its colour components is called dispersion of light
• The bending of light is measured by the index of refraction of the medium it passes through
• Wavelength affect the index of refraction of the material, causing light to disperse
• Angle of deviation refers to the amount of diversion of the refracted ray from its original direction as it leaves the prism
• red will bend the least when passed through prism
• 42 should be the angle of deviation between the rays from the sun and the outgoing rays to the observer so that s/he can see red color
