Sound waves force the medium particles to vibrate. Hence, these waves are known as mechanical waves. Sound waves propagate through a medium because of the interaction of the particles present in that medium.
Sound waves are called mechanical waves because they are produced by the motion of particle of a medium. Hence sound waves are called mechanical waves.
Sound waves are called mechanical waves because it requires material medium to propagate.
Sound is produced by the vibration of objects. When objects vibrate, it collides with the molecules in the...
Humming bees produce sound by vibrating their wings which is in the audible range. In case of pendulum the frequency is below 20 Hz which does not come in the...
Ultrasonic waves are those waves which have frequency more than 20 kHz.
Bats use ultrasonic waves to fly and search for their prey at night without colliding.
Bat produces ultrasound waves in...
Tone is the sound of single frequency.
Given,
Frequency, f = 500 Hz;
Distance, s = 450 m
Time period, T=?
T = 1/ f = 1 /500 = 0.002s
Therefore, the time interval will be 0.002...
No
Sound waves can propagate only through a medium. The two given situations are not scientifically identical because the motion of an observer relative to a medium is different in the...
Let the distance between the ship and the enemy submarine be ‘S’.
Speed of sound in water = 1450 m/s
Time lag between transmission and reception of Sonar waves = 77 s
In...
(c) Wavelength .
EXPLANATION:
When the sound wave is being sent by a tuning fork, its displacement amplitude, frequency and the time period will remain the same even if the temperature changes....
The correct answer is (a) P1= P2
EXPLANATION:
Let the cross-section area = A, if the intensity of the first wave at this cross-section = I₁ and of the second wave =...
