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
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.

Fill in the blank: The maximum displacement of a particle from its rest position in a wave is called the __________.
The distance between two consecutive crests of a wave is called the __________.
True or False: All electromagnetic waves are transverse waves.
True or False: The amplitude of a wave affects its speed.
True or False: The speed of a wave depends on the medium through which it travels.
True or False: The wavelength of a wave is inversely proportional to its frequency, if the speed is constant.
