Young's double slit experiment is carried out by using green, red and blue light, one color at a time. The fringe width recorded are `b_(G)`,`b_(R)` and `b_(B)` respectively. Then,

Yong's double-slit experiment is carried out by using green, red and blue light, one color at a time. The fringe widths recorded are beta_(G),beta_(R) and beta_(B) , respectively. Then

Young's double slit experiment is conducted using green red andt blue lights in succession. The magnitude of fringe widths obtained are beta_(G), beta_(R),beta_(B) respectively. The observations will be

In Young.s double slit experiment sodium light is replaced by blue lamp, then the fringe width

In Young's double slit experiment if wavelength of light is doubled without changing other conditions, the fringe width will
