basics of light[ charge and other points by adnan sir] Flashcards
what is mass? does it depend upon reference frame?
mass is the property of a body due to which it experiences or exerts gravitational force. yes[ M= Mo/underroot of 1- v2 /c2]
what is charge?
charge is the property of mass due to which it experiences or exerts electromagnetic force
what is quantization of charge
charge on any body is integral multiple of charge on fundamental particle
list the properties of charge?
charge is a scalar quantity
charge is conserved
charge is quantized
charge doesn’t depend on reference frame
what if charge is at rest
it produces electric field[ region around a charged particle within the force is exerted on other charged particles]
what is charge is in uniform velocity
it produce electric + magnetic field
what if charge is in accelerated state
it produce electric and magnetic field + it radiate energy [ electromagnetic wave]
which concave mirrors do we study about?
very thin. whose radius is grater than aperture
what is principle of conservation of charge
in an isolated system net charge always remains constant or conserved
what is the source of light?
accelerating charge
when is speed of light maximum
in vacuum
when does virtual image act as a virtual object for any mirror[ draw a diagram]
just draw it
what is a virtual object
rays are appearing to come
