Scattering of Light
Scattering of Light - When light passes through a substance or gas, a part of it is absorbed and the rest scattered away. The basic process in scattering is absorption of light by the molecules followed by re-radiation in different directi..

Tyndall Effect - The earth's atmosphere is a heterogeneous mixture of minute particles. These particles include smoke, tiny water droplets, suspended particles of dust and molecules of air. When beam of light strikes such air particles, the path of the beam becomes visible. Similarly the ..

Scattering Due to Polarisation - When a light wave falls on a transparent solid, it causes the electrons in the solid to oscillate periodically in response to of the incident waves. Since these oscillating charges act coherently or cooperatively there is a lack of scatterin..

When a beam of white light is passed through a medium containing particles of size nearly equal to the wavelength of light, the beam gets scattered. This scattered light is seen in a direction perpendicular to that of incidence and is found to..
Nature of Light
Nature of Light - Light is a form of energy and can be transformed into other forms of energy. You would have observed the path of 'a beam of light' inside a room. This beam is nothing but the scattered light produced by the dust particles and this ..

The effect of light on growth can be studied under 3 headings light intensity, light quality and duration of light. Growth is generally favoured by darkness, but light is indispensable because of its role in the manufacture of food. Young plants gro..

i really understood it and this teachers left me amazed and opened my eyes to the real world of math! Thanks a lot ,i mean it - Alina
I need tutoring from tutorvista till th end of my schooling. Tutors are not only experts they are brilliant enough to make a student like me understand the concepts of differentiation and functions.
Encouraging resource, great material to help students with studies. Really helpful... - Paul
My daughter use to study from personal tutor for Maths, but now when she is studying through TutorVista, she gets tutoring for Maths, Science, English.. everything at a price cheaper than the Math tutor she had.
Looking for More Help!
