Hey there !
A wavefront is a surface over which an optical wave has a constant phase. ... Such a surface which envelopes the particles that are in the same state of vibration is known as a wave front. The wave front at any instant is defined as the locus of all the particles of the medium which are in the same state of vibration.
Hope it helps you !

wavefront is a surface containing points affected in the same way by a wave at a given time
Wave Normal - a line perpendicular to the wavefront, representing the direction the waveis moving. Light Ray is the direction of propagation of the light energy.
