15. In Young’s double-slit experiment using monochromatic light, the interference pattern consists of a central . A. dark band with multi-colored bands on either side
B. bright band with alternate dark and bright bands on either side
C. dark band with alternate bright and dark bands on either side
D. white band with multi-colored bands on either side

In young's double slit experiment that uses monochromatic light the interference pattern formed has Central bright band with alternate dark and bright band That is option B.

Explanation: In this young experiment two small slits Namely a and b  are formed on the screen and a monochromatic light is focused on them. Wavelets come out of of this lets scintillating and overlapping each other. This we get from huyginns principal, thus forming alternate dark and bright bands with bright band at center and all bands are about one meter apart.

the temperature and the pressure affect solubility. temperature affects by changing the properties of the solvent. the increase in pressure increases solubility, the decrease in pressure decreases solubility.
