A narrow slit S transmitting light of wavelength `lamda` is placed a distance d above a large plane mirror as shown in figure. The light coming directly from the slit and that coming after the reflection interference at a screen `sum` placed at a distance LD from the slit. a. What will be the intensity at a poiint just above the mirror. i.e., just above O? b. At what distance from O does the first maximum occur?

A narrow slit S transmitting light of wavelength 'lambda' . Is placed at a distance d above a large plane mirror as shown. The light coming directly from the slit and that coming after the reflection interfere at a screen S placed at a distance D from the slit. at what distance from point O, the resultant intensity is maximum ? (there is a phase change of pi of reflection from the mirror)

In a Lloyds's mirror experiment as narrow slit S transmitting a light of wavelength lambda is placed 3 mm above a small plane mirror ( as shown). The light coming directly from the the slit and that coming after the reflection interfere on a screen placed at a distance of 90 cm from the slit. Length of mirror is 2 mm and the middle point of mirror is 2 mm from point P. If the mirror is shifted towards left then how does the fringe pattern on screen changes ?

A long narrow horizontal slit is placed 1 mm above a horizontal plane mirror. The interference between the light coming directly from the slit and that after reflection is seen on a screen 1.0 m away from the slit, Find the fringe-width if the light used has a wavelength of 700 nm.

A long narrow horizontal slit is placed 1 mm above a horizontal plane mirror. The interference between the light coming directly from the slit and that after reflection is seen on a screen 1.0 in away from the slit, Find the fringe-width if the light used has a wavelength of 700 nm.

A long horizontal slit is placed 1 mm above a horizontal plane mirror. The interference between the light coming directly from the slit and the after reflection is seen on a screen 1 m away from the slit. If the mirror reflects only 64% of the light falling on it, the ratio of the maximum to the minimum intensity in the interference pattern observed on the screen is

Two coherent narrow slits emitting light of wavelength lamda in the same phase are placed parallel to each other at a small separation of 3lamda the light is collected on a screen S which is placed at a distance D(gt gt lamda) from the slits the smallest distance x such that the P is a maxima.
