Caption:
Temperature perturbations in a magnetic flux sheet (strong field) due to waves excited by a horizontal motion at the bottom boundary. The excitation generates fast magneto-acoustic wave (predominantly magnetic) along with slow magneto-acoustic wave near the centre of the flux sheet. The fast wave is refracted, but the slow wave continues to propagate up.
