WebOrdinary reflection (as would occur at a mirror) would lead to a reflected beam having the in-plane wave vector component −k · sin θ. Due to the grating's phase modulation, one can have additional reflected components with in-plane wave vector components −k · sin θ ± 2 π / d. These correspond to the diffraction orders ±1. WebApr 6, 2024 · Complete answer: First of all let us check the characteristics of both the waves when reflected from denser and rarer medium. Generally the transverse waves are made up of crests and troughs. In a denser medium after the reflection, the phase difference happening will be 180 ∘.
