Two thin glass sheets (n = 1.5) are in contact on the other end and between the other end there is a sample when a wedgelike empty space containing air (n = 1.0) is formed (see picture). When the system is lighted with monochromatic light it can be seen an interference formation with dark and white lines spaced evenly.
- what line is seen at the contact point A, dark or light?
- how is the light line distance altered when the monochromatic light wavelength is altered?
- sample thickness is increased?
- the air is in the wedge is replaced by water (n = 1.3)?
- intensity of the monochromatic light is increased as the wavelength remains the same?
