Wave Optics is the treat­ment of light as a wave rather than as a ray or as a photon and is use­ful due to the wave/particle nature of light. Wave optics (in which I put geo­met­ric optics) was the first form of optics. (Later of course, the cor­puscle or particle nature of light became known — due to work by Max Planck and Albert Ein­stein and oth­ers.) Wave optics gov­erns all clas­sic­al optics (such as mir­rors), inter­fer­ence, dif­frac­tion etc. In fact, the tech­nique of inter­fer­o­metry is described using waves (this is a par­tic­u­larly power­ful tool for measurements).
