As the damping increases, the resonance amplitude decreases rapidly. Under the condition of fixed damping, qualitatively, the closer the frequency 𝜔 of the external driving force is to the intrinsic frequency 𝜔_0 of the system, the larger the steady state amplitude is.

The grating diffracted light intensity is distributed with the diffraction angle, with different colours representing different wavelengths. The animation parameter is the grating constant, which varies from large to small.
