If the frequency of a wave is 100Hz then the particles of the medium cross the mean position in one - Science - Sound

Question

If the frequency of a wave is 100Hz then the particles of the
medium cross the mean position in one second is

Aliya Francis · Answer

Answer is 200 times because frequency is the no of vibrations or
oscillation per second So every particle in a medium will cross the
mean position twice to complete 1 complete oscillation so
2×100 =200

If the frequency of a wave is 100Hz then the particles of the medium cross the mean position in one second is
