Standing Waves

Physics ⇒ Waves and Sound

Standing Waves starts at 10 and continues till grade 12. QuestionsToday has an evolving set of questions to continuously challenge students so that their knowledge grows in Standing Waves. How you perform is determined by your score and the time you take. When you play a quiz, your answers are evaluated in concept instead of actual words and definitions used.
See sample questions for grade 10
A pipe closed at one end and open at the other is 0.5 m long. If the speed of sound is 340 m/s, what is the fundamental frequency?
A pipe open at both ends has a length of 0.85 m. If the speed of sound in air is 340 m/s, what is the fundamental frequency of the pipe?
A standing wave is produced on a string of length 2 m. If there are 3 antinodes, what is the wavelength of the wave?
A string of length 0.8 m is vibrating in its third harmonic. What is the wavelength of the standing wave?
A string of length 1 m is vibrating in its fundamental mode. If the speed of the wave is 100 m/s, what is the frequency?
A string of length 1.5 m is vibrating in its second harmonic. How many nodes are present, including the ends?
Describe how a standing wave is formed on a string fixed at both ends.
Describe the difference between a node and an antinode in a standing wave.
Describe the difference in the harmonic series of a pipe open at both ends and a pipe closed at one end.
Describe the pattern of nodes and antinodes in the second harmonic of a pipe open at both ends.
Explain why no sound is heard at a node in a standing sound wave.
Explain why only certain frequencies produce standing waves on a string fixed at both ends.
Explain why standing waves do not transfer energy from one end of the medium to the other.
If the length of a string fixed at both ends is 1.2 m and the wavelength of the fundamental mode is 2.4 m, what is the frequency if the speed of the wave is 120 m/s?
If the speed of a wave on a string is 200 m/s and the string is 1 m long, what is the frequency of the second harmonic?
The third harmonic of a string fixed at both ends has a frequency of 300 Hz. What is the frequency of the fundamental?
What is a standing wave?
