Wave Speed
Physics ⇒ Waves and Sound
Wave Speed starts at 8 and continues till grade 12.
QuestionsToday has an evolving set of questions to continuously challenge students so that their knowledge grows in Wave Speed.
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 has a frequency of 500 Hz and a wavelength of 0.68 m. What is its speed?
A sound wave travels 1700 m in 5 seconds. What is its speed?
A sound wave travels at 330 m/s in air. If its wavelength is 1.1 m, 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 water wave has a wavelength of 2 m and a frequency of 0.5 Hz. What is its speed?
A wave has a speed of 250 m/s and a wavelength of 5 m. What is its frequency?
A wave on a string has a speed of 10 m/s. If the tension is quadrupled, what will be the new speed of the wave?

Describe how temperature affects the speed of sound in air.
Describe how the speed of a wave changes when it moves from a less dense to a more dense medium, such as from air to water.
Explain why electromagnetic waves can travel through a vacuum but sound waves cannot.
Explain why the speed of light is slower in glass than in air.
Explain why the speed of sound is generally greater in solids than in gases.
If the frequency of a wave is doubled but its speed remains constant, what happens to its wavelength?
What is the formula for the speed of a wave in terms of its frequency and wavelength?
