Wave Properties
Physics ⇒ Waves and Sound
Wave Properties starts at 7 and continues till grade 12.
QuestionsToday has an evolving set of questions to continuously challenge students so that their knowledge grows in Wave Properties.
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 sound wave travels at 340 m/s and has a frequency of 170 Hz. What is its wavelength?
A wave has a frequency of 50 Hz and a wavelength of 4 m. Calculate its speed.
A wave has a period of 0.2 seconds. What is its frequency?
A wave has a wavelength of 0.5 m and a speed of 250 m/s. What is its frequency?
A wave travels 600 meters in 3 seconds. What is its speed?
Describe what happens to the frequency and wavelength of a wave if its speed increases but the frequency remains constant.
Describe what is meant by the term 'crest' in a wave.
Explain the difference between longitudinal and transverse waves.
Explain why sound cannot travel through a vacuum.
If a wave has a frequency of 10 Hz and a wavelength of 3 m, what is its speed?
If the frequency of a wave increases, what happens to its wavelength (assuming the speed remains constant)?
If the period of a wave is 0.01 seconds, what is its frequency?
What is the formula for the speed of a wave?
What is the SI unit of frequency?
Which property of a wave determines its loudness?
Which property of a wave is measured in meters?
A string is vibrating in such a way that there are 3 complete wavelengths along its 1.2 m length. What is the wavelength of the wave on the string?
A water wave has a frequency of 5 Hz and travels at a speed of 2 m/s. How far apart are the wave crests?
A wave on a rope has a speed of 10 m/s and a wavelength of 2 m. If the frequency is doubled, what will be the new wavelength?
A wave travels from air into water. Its speed increases, but its frequency remains the same. Explain what happens to its wavelength and why.
