How does the amount of water in a glass affect the pitch of the sound it produces?

Answer:

the more water the higher the pitch the less water the lower it is

Answer:

The glass with the most water has the lowest pitch. The glass with the least amount of water has the highest pitch.

Explanation:Tapping the glasses causes the air to vibrate. When the air column is shorter, the air vibrates faster and the pitch is higher.

And done! :)))))))))

Heather is investigating the properties of light and how it travels. She places a glass on the windowsill and waits for the sun to shine on the glass and observes what happens. Next, she places a piece of cardboard in front of the glass. Which statement describes the results of her observations?

A Since glass is translucent, most of the light energy was reflected from the glass.
B When the cardboard was placed in front of it, the cardboard absorbed some of the light energy.
C The light from the sun was able to travel through the glass. When the cardboard was placed in front of the glass, it absorbed the light energy from the sun and converted it into heat energy.
D The glass absorbed the light and converted the light energy into heat energy. When the cardboard was placed in front of the glass, the heat was transferred from the glass to the cardboard.
When the sun hit the glass, the light energy was absorbed. When the cardboard was placed in front of the glass, it absorbed the light energy from the sun and converted it into heat energy.
