110. (a) We expect the center of the star to be a displacement node. The star has spherical symmetry and the waves are spherical. If matter at the center moved it would move equally in all directions and this is not possible. (b) We assume the oscillation is at the lowest resonance frequency. Then, exactly one- fourth of a wavelength fits the star radius. If λ is the wavelength and R is the star radius then λ = 4 R . The frequency is
