Wave Equation
Physics ⇒ Waves and Sound
Wave Equation starts at 9 and continues till grade 12.
QuestionsToday has an evolving set of questions to continuously challenge students so that their knowledge grows in Wave Equation.
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 12
A sound wave in air has a wavelength of 0.5 m and a speed of 340 m/s. What is its frequency?
A string has a mass per unit length of 0.02 kg/m and is under a tension of 80 N. What is the speed of a wave on this string?
A string of length 2 m is fixed at both ends and vibrates in its fundamental mode. If the speed of the wave on the string is 100 m/s, what is the frequency of the fundamental mode?
Describe the physical meaning of the term 'node' in the context of standing waves.
Explain why the wave equation is linear and discuss the significance of this property.
If a wave has a frequency of 500 Hz and a wavelength of 0.68 m, what is its speed?
If the amplitude of a wave is doubled, what happens to the speed of the wave?
State the principle of superposition as it applies to solutions of the wave equation.
