Sand grains rest on a horzontal plate. The plate vibrates in the vertical plane with SHM of amplitude 1.5mm at a fixed frequency with acceleration equal to free fall (9.8ms^-2).
What will happen to the grains of sand when the frequency of vibration is increased?
I am unsure of how to tackle this problem. Will the amplitude of oscillation decrease? My working is below:
max acceleration = amplitude*((2*pi*f)^2)If f increases, with max acceleration the same, the amplitude decreases. Is this reasoning and answer correct?
Thanks
