Three pendulums with strings of the same length and bobs of the same mass are pulled out to angles θ1, θ2, and θ3, respectively, and released. the approximation sin θ = θ holds for all three angles, with θ3 > θ2 > θ1. how do the angular frequencies of the three pendulums compare?

Are formed where bumps from two surfaces come into contact ?
