What is sustained interference pattern?
sustained interference are those in which the position of bright and dark fringes are fixed on the screen.
Why two distant flash lights do not produce interference fringes?
to produce interference pattern the sources should be coherent but two independent sources cannot produce such pattern. hence they won't produce interference fringes
Why an oil film floating on water has coloured pattern?
ordinary light is composed of seven colours where each colour has definite wavelength. so when ordinay light fallls on a thin oil floating in the surface of water, constructive interference take place for one colour at a certain point, while destructive interference occurs for the other colours in this way constructive interference for different colour takes place at different point. Hence a series of coloured fringes or pattern is seen
What conditions are necessary for two light waves to form an interference pattern of bright lines and dark areas?
State two necessary conditions for formation ofinterference fringes.
What happens to interference pattern if wavelength of light is decreased?
the light must be coherent - which happens when a single beam of light is split

Can visible light produce interference Fringes.Explain?
yes, white light can produce interferance fringes because white colour consist of seven colours each spectral colour produces its own interferance fringes pattern.

Why does light produce a pattern similar to an interference pattern when it passes through a single slit?
This phenomenon occurs due to light's wave-like properties. Via diffraction, the bending of light wave about an obstacle, the light wave will interfere and exhibit dark and bright fringes on a screen as a result of this interference.
Why straight line fringes are formed in air wedge arrangement?
Each fringe in the pattern is produced by the interference of light rays reflected from sections of the wedge having same thickness.The locus of points having the same thickness lies along lines parallel to the contact edge.So fringes are straight.
Conditions for interference of light?
You mean conditions for getting sustained interference pattern with clarity. 1. Sources have to be monochromatic and coherent 2. Two sources have to be so close as far as possible 3. The screen is to be kept at far distance
What is a reason of no interference pattern?
interference happens if and only if the waves entering the double slits are synchronous (having same nature and same wavelength) and coherent (waves between the two waves are constant at anytime i.e. starting at the same time)... so if these conditions are valid, interference occurs, otherwise no interference will happen.
Is the fresnel biprism experiment better than young's double slit experiment?
yes,because in fresnel biprism the fringe width can be increased so that the dark and bright fringes can be seen clearly by naked eyes..but there is no such problem in fresnel biprism.. in young's double slit experiment, the pattern is the superposition of interference and diffraction. but in fresnel biprism it is purely interference pattern.
