Light consists of

In 1873 , James Maxwell proposed that visible light consists of electromagnetic waves. According to Maxwell's theory, an electromagnetic wave has an electric. Field component and a magnetic field compound. Which of the followong is incorrect regarding the two components?

A beam of light consists of two wavelengths, 6300Å and 5600Å . This beam of light is used to obtain an interference pattern in YDSE. If 4^("th") bright fringe of 6300Å coincides with the n^("th") dark fringe of 5600Å from the central line, then find the value of n.

In a Young's double slit experiment, if the incident light consists of two wavelengths lamda_(1)andlamda_(2) , the slit separation is d, and the distance between the slit and the screen is D, the maxima due to the two wavelengths will coincide at a distance from the central maxima, given by :

In YDSE a parallel beam of incident light consists of two wavelengths lambda_(1)=4000Å and lambda_(2)=5600Å . The minimum distance y on the screen, measured from the central axis, where the bright fringe due to two wavelengths coincide is (nlambda_(1)D)/(d) . Find n.

How many colours does white light consist of and what are they?

Young's experiment proves that light consist of

_________ light is a composite light which consists of light of various colours or wavelengths.

In Young.s double slit experiment, slits are separated by 2 mm and the screen is placed at a distance of 1.2 m from the slits. Light consisting of two wavelengths 6500Å and 5200Å are used to obtain interference fringes. Then the separation between the fourth bright fringes of two different patterns produced by the two wavelengths is
