give the full notes of dispersion and scattering of light
Answers
Answer:
The angle between the normal and the refracted ray is known as the angle of refraction. The splitting of white light into its constituent colours is called dispersion of light. Light disperses and creates a rainbow effect, when it propagates and refracts in a prism
mark me as brainliest........
☑️ When a beam of white light is passed through a prism, it is splitted into a band of seven colours. The band of these seven coloured components of the white light is called spectrum.
☑️ The phenomenon of splitting up of white light into its constituent seven colours when it passes through certain transparent refractory medium like prism is called dispersion of that white light.
☑️ When light wave passes through the atmosphere, it is absorbed by the molecules of air and these molecules further emit visible radiation in all directions and this phenomenon is called scattering of light.
☑️ According to Rayleigh, the intensity of light scattered is inversely proportional to the fourth power of the wavelength of the incident light.
☑️ Res light is scattered the least whereas violet, indigo or blue scatter more.
☑️ Red coloured light is least deviated and violet coloured light has maximum deviation when a white ray of light passes through a prism.
☑️ The angular deviation is different for different constituent colours when a white light passes through a prism.
☑️ When a narrow beam of white light is incident on a glass prism, the emergent rays of light when fall on a screen, a band of seven different colours is seen on the screen in the sequence : VIOLET, INDIGO, BLUE, GREEN, YELLOW, ORANGE and RED (abbreviated as VIBGYOR) from bottom to top.
✍️ SUCCESS CORNER ✍️
✳️ STUDY THE TOPIC "DISPERSION AND SCATTERING OF LIGHT" FROM CLASS 10 CBSE NCERT BOOK. IT WILL BE THE BEST CHOICE.
✳️ LEARN AGAIN AND AGAIN THE THEORIES AND CONCEPTS.
✳️ PRACTICE NUMERICALS FROM THE OVERALL CHAPTER - "LIGHT".
