Vedclass · Answer

(A) muslin cloth consists of a fine mesh of threads,creating a large number of tiny,closely spaced slits.When white light passes through these fine slits,it undergoes diffraction.Since the diffraction pattern depends on the wavelength of light,different colours are diffracted at different angles.This separation of white light into its constituent colours results in the observation of a coloured spectrum.Therefore,both the Assertion and the Reason are correct,and the Reason is the correct explanation of the Assertion.

Assertion: $A$ coloured spectrum is seen when we look through a muslin cloth.
Reason: It is due to the diffraction of white light on passing through fine slits.

When light is incident on a diffraction grating,the zero-order principal maximum will be:

$A$ beam of light of $\lambda = 600 \, nm$ from a distant source falls on a single slit $1 \, mm$ wide and the resulting diffraction pattern is observed on a screen $2 \, m$ away. The distance between the first dark fringes on either side of the central bright fringe is:

The condition for obtaining secondary maxima in the diffraction pattern due to a single slit is:

Light of wavelength $600 \,nm$ is incident normally on a slit of width $0.2 \,mm$. The angular width of the central maxima in the diffraction pattern is (measured from minimum to minimum):

To observe diffraction,the size of the obstacle
