Red light of wavelength 633 nm from a helium-neon laser passes through a slit 0.310 mm wide. the diffraction pattern is observed on a screen 3.40 m away. define the width of a bright fringe as the distance between the minima on either side. (a) what is the width of the central bright fringe? (b) what is the width of the first bright fringe on either side of the central one?

radiation

explanation:

heat is transmitted by radiation

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
