Applications of Sound Waves
Physics ⇒ Waves and Sound
Applications of Sound Waves starts at 9 and continues till grade 12.
QuestionsToday has an evolving set of questions to continuously challenge students so that their knowledge grows in Applications of Sound 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 10
Describe how dolphins use sound waves to communicate and navigate.
Describe how sound waves are used in cleaning medical instruments.
Describe how sound waves are used in underwater navigation by submarines.
Describe one industrial application of ultrasound.
Explain how bats use sound waves for navigation.
A bat emits a sound wave and receives the echo after 0.02 seconds. If the speed of sound in air is 340 m/s, how far is the object?
A dolphin emits a sound that travels to a fish 300 m away and returns in 0.4 seconds. What is the speed of sound in water?
A ship sends a sound wave to the sea bed and receives the echo after 4 seconds. If the speed of sound in water is 1500 m/s, calculate the depth of the sea at that point.
