Energy Transfer in Waves 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 Energy Transfer in Waves.
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

True or False: Electromagnetic waves can transfer energy through a vacuum.
True or False: In a longitudinal wave, the particles of the medium move perpendicular to the direction of energy transfer.
True or False: In a transverse wave, energy is transferred parallel to the direction of particle vibration.
True or False: The energy carried by a wave is always conserved as it travels through a medium.
