When steam is passed through red hot coke:

When no current is passed through a conductor,

Draw a ray diagram to show the refraction of a monochromatic ray through a prism when it suffers minimum deviation. How is the angle of emergence related to the angle of incidence in the position.

A plane polarised light is passed through a polaroid, when the polaroid is given one full rotation about the direction of light, then

A ray of white light is passed through a glass prism and a spectrum is obtained on a screen. (a) Name the seven colours of the spectrum in order. (b) Do the colours have the same width in the spectrum ? (c) Which colour of the spectrum of white light deviates (i) the most, (ii) the least?

White light is passed through a prism of angle 4^(@) . If the refractive indices for red and blue colours are 1.641 are 1.659 respectively, then calculate the angle of deviation between them, also calculate the dispersive power.

White light is passed through a prism of angle 5^@ . If the refractive indices for red and blue colours are 1.641 and 1.659 respectively, calculate the angle of deviation between them, also calculate the dispersive power.

When a ray of sun light passes through the prism, each colour of light has its own speed in the glass. The seven colours come out of the prism with different angles of deviation. Red deviates least and blue deviates maximum. Thus a prism can disperse a white light into seven colours which is called colour spectrum. For a thin prism, the angle of deviation is given as delta=(n-1)A . The angle of dispersion is given as phi=delta_(v)-delta_(r) . The dispersive power of a prism is omega=(phi)/(delta_("mean"))=(phi)/(delta_(y)) Using the above ideas, give answer the following questions. A prism has R.I. for violet and red n_(v)=1.523, n_(r)=1.5145 . If the angle of prism is A=2^(@) the dispersive power of the prism is :
