Using the WKB approximation, we obtain the frequencies of various types of perturbation both analytically and numerically for arbitrary brane tension. We thus extend earlier analytical results which were derived for a brane of small tension.17 pages, uses bibTeX, 5 figuresHigh Energy Physics - TheoryGeneral Relativity and Quantum Cosmologytext
