A system of two identical masses connected by identical springs, as shown in the figure, oscillates along the vertical direction.
The ratio of the frequencies of the normal modes is
1
\(\sqrt{3-\sqrt{5}}: \sqrt{3+\sqrt{5}}\)
2
\(3-\sqrt{5}: 3+\sqrt{5}\)
3
\(\sqrt{5-\sqrt{3}}: \sqrt{5+\sqrt{3}}\)
4
\(5-\sqrt{3}: 5+\sqrt{3}\)
