Sound Waves and Pipe Fundamentals

The video tutorial explores the fundamental frequency of a pipe open at both ends and how it changes when the pipe is half submerged in water. Initially, the wavelength and frequency are calculated for the pipe open at both ends. The velocity of sound is discussed in relation to frequency. When the pipe is submerged, the effective length changes, but the fundamental frequency remains the same as when the pipe is open at both ends.

What is the fundamental frequency of a pipe open at both ends in air?

• It is half the wavelength.

• It is the same as the velocity of sound.

• It is determined by the length of the pipe.

• It is twice the wavelength.

How is the fraction of wavelength inside a pipe open at both ends expressed?

• Lambda by 5

• Lambda by 3

• Lambda by 4

• Lambda by 2

What is the relationship between velocity of sound, wavelength, and frequency?

• V = lambda / F

• V = F / lambda

• V = F + lambda

• V = lambda * F

When the pipe is half submerged in water, what fraction of the wavelength is inside the pipe?

• Lambda by 4

• Lambda by 3

• Lambda by 2

• Lambda by 5

What happens to the wavelength when the pipe is half submerged in water?

• It doubles.

• It triples.

• It halves.

• It remains the same.

What is the new frequency when the pipe is half submerged in water?

• It is triple the original frequency.

• It remains the same as the original frequency.

• It is double the original frequency.

• It is half of the original frequency.

How does the length of the pipe affect the fundamental frequency when submerged?

• The length triples the frequency.

• The length does not affect the frequency.

• The length doubles the frequency.

• The length halves the frequency.

What is the effect of submerging the pipe on the velocity of sound?

• The velocity of sound increases.

• The velocity of sound remains unchanged.

• The velocity of sound becomes zero.

• The velocity of sound decreases.

What is the relationship between lambda and lambda dash when the pipe is submerged?

• Lambda dash is double of lambda.

• Lambda dash is half of lambda.

• Lambda dash is triple of lambda.

• Lambda dash is equal to lambda.

What is the conclusion about the fundamental frequency when the pipe is half submerged?

• It remains the same.

• It becomes zero.

• It halves.

• It doubles.
