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 8
Describe the difference between transverse and longitudinal waves.
Describe what happens to the frequency of a wave if the period increases.
Describe what happens to the wavelength of a wave if its speed increases but the frequency stays the same.
Explain what is meant by the term 'crest' in a wave.
A sound wave travels at 340 m/s and has a frequency of 170 Hz. What is its wavelength?
A water wave has a wavelength of 0.5 m and a frequency of 4 Hz. What is its speed?
A wave has a frequency of 10 Hz and a wavelength of 2 m. What is its speed?

(1) Increases
(2) Decreases
(3) Stays the same
(4) Doubles
Which of the following best describes a longitudinal wave?

True or False: All electromagnetic waves are transverse waves.
True or False: All waves transfer matter from one place to another.
True or False: In a longitudinal wave, the particles of the medium move parallel to the direction of the wave.
