What principle is responsible for light spreading as it passes through a narrow slit?
Diffraction
Why narrow slits are taken in Young's double slit interference experiment?
to provide sufficient diffraction.
What happens if width of the slits increases in double slit diffraction experiment?
Silicon, Germainium, Tin, Lead, Ununquadium.
What is observed when a red filter is placed between a source of light and a double slit?
A red slit.
What is the diffraction of light waves?
Diffraction of light waves is caused by the density of the medium through which the light is passing. Diffraction results when light travels from rarer to denser medium.

Why does the spectroscope have a slit?
The purpose of a slit is to cause diffraction of the light. This means the light spreads out in all directions, as opposed to entering a large hole where the light would pass straight through in its original direction.
What happens if width of the slits increases in double slit diffraction experiment?
Silicon, Germainium, Tin, Lead, Ununquadium.
What factors affecting diffraction?
Wavelength width of the slit
What is observed when a red filter is placed between a source of light and a double slit?
A red slit.
Why should slit width be approximately equal to wavelength of light for diffraction?
This is to maximize the effect of diffraction. The wavelength of the photon can be regarded as its 'size' . If it is too large then the slit is just to small for it and most of the photons will be absorbed or reflected. If it is far too small then the slit, in comparison, will be very large so most photons do not even notice its presence and will just continue on their merry way without interacting with it.
The amount of diffraction and thus the resolution of the scope depends upon?
the amount of diffraction depends on the opening of the slit and the wavelength of the light being used... resolution of diffraction on the screen also depends on the slit opening and the wavelength, but it more specifically depends on the angle at which the lit is shone, more on resolution, check out criterion for resolution........physics textbook do alot of clear explanation on that, check out physics for scientists and engineers, serway
Is interference a special case of diffraction or diffraction is a special case of interference?
neither is the case since diffraction involves the bending of waves upon contact or lack thereof of a physical boundary. a double slit experiment works on the basis of diffraction and also forms a distinctive interference pattern so in this case the two are related and the diffraction causes the interference but isn't necessarily a case of interference.
What are three ways that waves change directions?
Reflection, refraction, and diffraction. Reflection is most common, when we see ourselves in the mirror. Refraction is evident when you insert a straw into a clear liquid (7-up, for example) and see the straw bend at the surface apparently. Diffraction is when light passes through a slit or opening, an interference pattern appears much wider than the slit on the other side.
What is the diffraction of light waves?
Diffraction of light waves is caused by the density of the medium through which the light is passing. Diffraction results when light travels from rarer to denser medium.
Diffraction is the tendency of light to?
Diffraction is the tendency of light to spread around corners.
