temporal coherence

rate

(Expression) if the phase difference of the waves crossing the two points lying along the direction pf propagation of the beam is time independent .

Usage: suppose the phases pf the waves crossing p and q at any instant t1 are $1 and $2 . And the same when measured at the instant y2' and $'1 and $'2.The beam is said to be coherent if $2-$1=$'2-$'1
