Question

(100 Points) Class XI Assertion (A) : An aircraft, passing near a building can, at times, cause vigorous
vibrations of its window panes,
Reason (R) : When resonance occurs the amplitude of vibrations becomes large.​

Answer 1

Answer:

Hello mate

Explanation:

Assertion is correct but reason

is not correct .

correct reason is

If the frequency of the sound produced by the engine of aeroplane passing over building is equal to the natural frequency of windows of the building, then resonance takes place and causes the rattling of window.

Answer 2

${\boxed{\underline{\tt{ \orange{Required \: \: answer:-}}}}}$

ASSERTION AND REASON both are CORRECT

${\underline{\underbrace{\tt{Understanding \: \: the \: \: concept}}}}$

Assertion and Reason:-

It happens because glass resonances at frequencies we can hear. The resonant frequency of the glass changes with its thickness.

When energy at that frequency meets the glass, it causes the glass to vibrate like a drum head.

enough vibration can cause the glass to shatter!

Airplanes create a lot of noise due to the huge engines fitted in it. The vibrations produced by the noise waves makes the sonorous glass vibrate, giving it a shaking expression.

As it is also depends on air beccause air moves so fast like wind, It means that the pressure present there is low in comparision to the air inside a closed structure usually made of wood or cement.
