What is the concept of points in phase in wave mechanics?

Points that are separated by a half wavelength

Locations on a wave that are at the same stage in their periodic motion (correct)

Points that are at different stages in their periodic motion

Points that are moving in opposite directions

What is the condition for two points on a wave to be in phase?

They are moving in the same direction

They are separated by a half wavelength
