Intensity pattern for single slit diffraction:
संबंधित प्रश्न
In deriving the single slit diffraction pattern, it was stated that the intensity is zero at angles of nλ/a. Justify this by suitably dividing the slit to bring out the cancellation.
Draw the intensity pattern for double slit interference.
State differences between interference and diffraction patterns.
(i) State the essential conditions for diffraction of light.
(ii) Explain diffraction of light due to a narrow single slit and the formation of pattern of fringes on the screen.
(iii) Find the relation for width of central maximum in terms of wavelength 'λ', width of slit 'a', and separation between slit and screen 'D'.
(iv) If the width of the slit is made double the original width, how does it affect the size and intensity of the central band?
Derive the relation a sin θ = λ for the first minimum of the diffraction pattern produced due to a single slit of width ‘a’ using light of wavelength λ.
Which items are used to form the narrow, uniform slit?
What appears when the slit is aligned parallel to the filament?
What fringe pattern is observed through a red colour filter?
Why is the fringe pattern wider with a red colour filter?
Why do coloured fringes appear with white light and no filter?
