Can a beam of white light when passed through a hollow prism give spectrum? Explain.

A beam of white lighe passing through a hollow prism gives no spectrum.

A beam of white light is incident on a hollow prism of glass. Then

The band of seven colours obtained on a screen when white light passes through a prism is called spectrum. ____

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?

If a beam of light is passed through true solution, then it is

A thin prism of angle 6.0^@, omega'=0.07 and mu_y'=1.50 is combined with another thin prism having omega = 0.08 and mu_y = 1.60 . The combination produces no deviation in the mean ray. (a) Find the angle of the second prism. (b) Find the net angular dispersion produced by the combination when a beam of white light passes through it. (c) If the prisms are similarly directed, what will be the deviation in the mean ray ? (d) Find the angular dispersion in the situation described in (c).

Statement-1 : When a white light passes through a prism it forms a spectrum of seven colours. Statement-2 : The refractive index for different colour of light is different for the material of prism.

When a beam of white light is passed through sodium vapours and then through a spectrometer, spectrum so obtained has two dark lines present in the yellow region. This spectrum is called :

A glass prism of angle A = 60^(@) gives minimum angle of deviation theta ~~ 30^(@) with the maximum error of 1^(@) when a beam of parallel light passed through the prism during an experiment. Find the permissible error in the measurement of refractive index mu of the material of the prism.

A narrow beam of white light goes through a slab having parallel faces.
