    B Doubts about Light...

    Hello There:woot:, I have basic doubt about light propagation .So I'm hoping to get some help here. The problem is ...Let us assume two frames, 'MOVING FRAME'[one moving with a certain velocity(constant)] and 'REST FRAME'[one wrt to which the first frame is moving]. If now moving frame emits a...

    B Michelson-Morley Exp. and Laws of Reflection

    Hello there, I have a problem with this image from the Michelson Morley experiment in which one tries to calculate the time taken by the light beam to traverse the arm of interferometer perpendicular to the velocity of the frame in 'ether'. So the problem is, Are laws of reflection being...

    B Planarity of Central Force Motion

    Hi There!!, I'm here just to know an answer to a question that is bothering me for a while now. We know that motion of a body under the influence of central force with given center [say A] is planar . I was thinking whether this is possible even when body is allowed to move under the influence...

    B Energy, charge and electric field

    Hi there, Im familiar with the concept that electric field has associated energy with it Now if in space an electron apppeared at some instant t=0 then electric field will not be established instantaneously but will propagate at speed of light through space As electric field is bieng...

    B Photon and electron collision

    I have read in textbook that if a photon were to collide with a free electron it's an impossible situation for photon to get completely absorbed by an electron . The situation seems possible by conservation of energy but im not able to understand the true reason behind the statement .is there...

    B Color and Wavelengths

    I have read that color of light percieved by us depend on its wavelength since light is wave and also electron has wave like character that means electron has wavelength .Does that mean that electron has a color associated with it . I think its not but why .also I'm not able to understand...

    B Problem with light grazing along the liquid surface

    Let's suppose we have a cuboidal tank filled with liquid of density rho,such that Critical angle of medium is (Ic) now it's Clear that light rays from the medium that strike at proper critical angle will Graze along the surface Now if someone would be along the path of the rays receiving...

    B Gauss' Law Problem

    I WAS THINKING ABOUT A REGION OF SPACE WITH ELECTRIC FIELD ALONG POSITIVE X DIRECTION AND Varying WITH SPACE COORDINATE(x) NOW IF ONE IMAGINES A CUBE IN SPACE SUCH THAT FIELD CROSSES ITS TWO FACES AT RIGHT ANGLES ,A SIMPLE Application of...
