The pitch of a sound is its highness or lowness. the higher the frequency of a sound wave is, the higher its pitch.

the waves shown below represent sound waves. which of the waves would have the highest-pitched sound?

1st wave

Explanation:

The higher the frequency of the wave , higher the pitch.

To find the highest-pitched sound we should find the wave with the highest frequency.

wave's frequency is the number of cycles that are completed in a certain amount of time

If we consider the number of oscillations in a given time of 0.01 seconds , wave 1 has the highest number.

therefore wave 1 has the highest frequency , so the pitch.

the temperature in kelvin of 2.0 dm3 of an ideal gas is doubled and its pressure is increased by a factor of four. what is the final volume of the gas

the answer is 12 as i may remember
