A lineafized theory ofmagnetoatmospheric waves is developed where the restoring forcesare those of compressibility and magnetic pressure. An equation for resonance is derived. Reflectionand tunneling of upward propagating Alfvén waves in an ideal Magnetoatmosphere are considered. Itis shown that the magnetic field produces a reflecting nonabsorbing critical layer. Below the criticallayer, the solution of the problem can be written as a linear combination of an upward and a downwardpropagating wave and above it the solution decays exponentially with the altitude. The location of thecritical layer and the magnitude of the reflection coefficient are determined and the conclusions arediscussed in cormeetion with the heating mechanism of the solar atmospher
