Question

If you want to play a tune on wine glasses, you’ll need to adjust the oscillation frequencies by adding water to the glasses. This changes the mass that oscillates (more water means more mass) but not the restoring force, which is determined by the stiffness of the glass itself. If you need to raise the frequency of a par- ticular glass, should you add water or remove water?

Answer 1

Answer:Reducing mass i.e. water

Step-by-step explanation:

Frequency For given mass in glass is given by

`f=(1)/(2\pi )\sqrt{(k)/(m)}`

where k =stiffness of the glass

m=mass of water in glass

from the above expression we can see that if mass is inversely Proportional to frequency

thus reducing mass we can increase frequency
