A thin slice is cut out of a glass cylinder along a plane parallel to its axis. The slice is placed on a flat glass plate as shown in Figure. The observed interference fringes from this combination shall be
Shape Of Interference Fringes In Ydse
A beam of electrons with speed v_(0) passes through double slits and then is allowed to strike a fluorescent screen. An interference pattern is observed on the screen. The electrons are instead replaced by protons moving with speed v_(0) Compared to electrons at the same speed, what happens to the spacing of the interference fringes on the screen?
A monochromatic light source S of wavelength 440 nm is placed slightly above a plane mirror M as shown . Image of S in M can be used as a virtual source to produce interference fringes on the screen. The distance of source S from O is 20.0 cm, and the distance of screen from O is 100.0 cm (figure is not to scale). If the angle theta = 0.50 xx10^(-3) radians, the width of the interference fringes observed on the screen is –
Assertion: A glass hemisphere is placed on a flat plate as shown. The observed interference fringes from this combination shall be circular. Reason: In all cases fringes are circular.
A point sources S emitting light of wavelength 600nm is placed at a very small height h above the flat reflecting surface AB (see figure).The intensity of the reflected light is 36% of the intensity.interference firnges are observed on a screen placed parallel to the reflecting surface a very large distance D from it. (A)What is the shape of the interference fringes on the screen? (B)Calculate the ratio of the minimum to the maximum to the maximum intensities in the interference fringes fromed near the point P (shown in the figure) (c) if the intenstities at point P corresponds to a maximum,calculate the minimum distance through which the reflecting surface AB should be shifted so that the intensity at P again becomes maximum.
