What is the discovery of Thomas Young about light?
thomas young carried out his (double slit experiment) where he discussed the interference of light waves using monochromatic light . the 2 slits act as 2 coherent sources which emit light with same amplitude frequency . interference fringes appear due to superposition of light . this experiment is also used to determine the wavelength of monochromatic light. from the relation y=wavelength*distance between 2 slits /distance between the 2 slits and the screen where the fringes appear . where y is the distance between 2 successive bright or dark fringes.
What is meant by interfringes?
Interfringes means the distance between the vertexes of two adjacent fringes of the same nature (antinodal or nodal curves)
What happens when a silver plate is used in newton's rings experiment?
fringes will shift because path differnce of wavelength/2 will remove.
What is fizeau fringes?
it is interference produced from light entering an inclined plate , it is used to measure small distances, the distance can be measured using the equation: (delta) x= lambda/2 alpha Alpha is the angle between the inclined plate and the horizontal surface, x is the distance from the point of contact to the spacer inclining the plate, y is the distance being measured.
How would the angular separation of interferences fringes in young's double slit experiment change when the distance of separation between the slits and the screen is doubled?
Note that bandwidth = lamda D / d and bandwidth = D @ Here @ is the angular separation. So @ = lamda D / D d = lambda / d So as D is not there in the expression the angular separation remains the same though the distance between slits and the screen is doubled.
The mirror of Michelson interferometer is moved a length equal to the wavelength of incident light Find the shift in fringes?
two fringes .... since each half a wavelength distance corresponds to a fringe change!

What happens to the distance interference fringes if the separation between the slits is increased?
decreases

What is the difference between fringes and bangs?
it is the same
Why is an extended source used in newtons ring experiment?
extende source is required to get nearly parallel rays of light
Difference between Newton's ring fringes and biprism fringes?
Biprism produce straight fringe systems while Newton's rings are circular fringe patterns.
Why are the fringes called non localized?
When the reflected ray of resulting interference is parallel by which fringes formed at infinity then this type of fringes is known as non localised fringes
What does fringes mean?
fringes are bangs (worn as a hairstyle)
When was The Fringes of the Fleet created?
The Fringes of the Fleet was created in 1916.
How can you use the word fringes in a sentence?
The movie had a song about a surry with fringes on the top. The mountain man wore a leather coat with fringes.
