Two slits are 0.135 mm apart. A mixture of red light (λ= 445 nm) falls on two slits. If an interference pattern is produced on a screen 2.8 m away, find the distance between the 1st red fringe and the 1st blue- violet fringe.

the order for strong to weak forces such as

strong nuclear force → electromegnetic force → weak nuclear force → gravitational force

the fundamental forces are those forces that act between to objects or element to make interactions. there are four types of fundamental forces such as strong and weak nuclear forces (due to protons and electrons), electromagnetic force (due to the motion of electrons) and gravitational force (due to orbital movement of the planet). if these forces are arranged on the basis of their maximum strength then the order is

strong nuclear force → electromegnetic force → weak nuclear force → gravitational force
