How would the diffraction pattern of a single slit be affected when the monocromatic source of light is replaced by white light?

11What is the explaination given for the diffraction pattern observed while using a monochromatic source of light?
1diffraction pattern cn be obtained by placing any obstacle in the path of the light
1the central band is white and thn the red fringe is wider thn violet fringe nd so on.....u wld get rainbow colours
1dude. I meant , you'd have done this experiment while studying no ? plz explain that . I dint get what u said now. :(
62oops i was doing somthing else altogether... din see that ;)
Sorry honey and srinath .. confused everyoe... I am reading and writing two different things!
I was doing a YDSE :P
1Nishant you've done practicals no ? please explain the setup and all , If possible, briefly.
1at the center u will get max of each wavelenth------thus white;
as we will move away from center u might gradually be able to see different colors
(as the maximas are differently positioned);
but u know that intensity decreases very rapidly in case of diffraction,so gradual appearence
of colors will be very faint(u wont be able to see colors after 3rd order).
1Diffraction is normally taken to refer to various phenomena which occur when a wave encounters an obstacle. It is described as the apparent bending of waves around small obstacles and the spreading out of waves past small openings.Very similar effects are observed when there is an alteration in the properties of the medium in which the wave is travelling, for example a variation in refractive index for light waves or in acoustic impedance for sound waves and these can also be referred to as diffraction effects. Diffraction occurs with all waves, including sound waves, water waves, and electromagnetic waves such as visible light, x-rays and radio waves. As physical objects have wave-like properties, diffraction also occurs with matter and can be studied according to the principles of quantum mechanics.
While diffraction occurs whenever propagating waves encounter such changes, its effects are generally most pronounced for waves where the wavelength is on the order of the size of the diffracting objects. The complex patterns resulting from the intensity of a diffracted wave are a result of the superposition, or interference of different parts of a wave that traveled to the observer by different paths.
11Honey, I'm not asking the result.....I'm asking the process. [1]
11Not in syllabus but this explaination will help a lot more than u imagine[1]
11I'm asking it here bcos i'm not able to comprehend it from my book. Anyone else?
1itz like interferance bt in it the width of the fringes goes on decreasing on moving up nd down........it is max at the center
11Can anyone pls explain what really happens in diffraction?
