    Correct Option - 2


    Detailed Solution:

                  x = 10   2 ? ( n t ? x ? ) c m

                  V (wave velocity) =   ? ? 2 ?

                  vmax = 10 * 2p n

                  10 * 2pn = 4 *   ? ? 2 ?

                  10 * 2pn =   4 2 ? ? n ? 2 ?

                   x = 5?

In an experiment to determine the velocity of sound in air at room temperature using a resonance tube, the first resonance is observed when the air column has a length of 20.0 cm for a tuning form of frequency 400 Hz is used. The velocity of the sound at room temperature is 336 ms-1. The third resonance is observed when the air column has a length of ____________cm.

According to Concept of resonance tube, we can write

λ 4 + e = l 1 a n d     3 λ 4 + e = l 2 ⇒ λ 2 = l 2 − l 1 ⇒ V 2 ν = l 2 − l 1

⇒ l 2 = v 2 ν + l 1 = 3 3 6 4 0 0 + 0 . 2 0 = 0 . 8 4 + 0 . 2 0 = 1 . 0 4 m = 1 0 4 c m

The TV transmission tower at a particular station has a height of 125 m. For doubling the coverage of its range, the height of the tower should be increased by

According to question, we can write

  d = 2 h R ⇒ d 2 d 1 = h 2 h 1 ⇒ h 2 = ( d 2 d 1 ) 2 h 1 = ( 2 1 ) 2 × 1 2 5 = 5 0 0 m

Increment in height of tower = h2 – h1 = 500 – 125 = 375 m

A signal containing multiple frequencies is shown in figure A. It is passed through 2 different filters and then outputs are shown in figure B & C.

Low pass filter will allow low frequency signal to pass while high pass filter allow high frequency to pass through

A source of sound S is moving with a velocity of 50 m/s towards a stationary observer. The observer measures the frequency of the source as 1000 Hz. What will be the apparent frequency (in Hz) of the source when it is moving away from the observer after crossing him? (Take speed of sound in air as 350 m/s)
