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 11
A sound wave has a frequency of 500 Hz and a wavelength of 0.68 m. What is its speed?
A string vibrates at a frequency of 120 Hz and produces waves with a wavelength of 2.5 m. Calculate the speed of the wave.
