Chapter 9: Problem 212

Match the information given in Column-I with that given in Column-II Column-I (A) Mechanical waves (B) Electromagnetic waves (C) Longitudinal waves (D) Pressure waves Column-II 1\. Transverse only 2\. Can be transverse or longitudinal 3\. Required a medium to propagate 4\. Must be elastic parameters dependent

Short Answer

Expert verified
(A) matches with 3 and 4, (B) matches with 1, (C) matches with 2 and 3, (D) matches with 3 and 4.

Step by step solution

01

Analyze Mechanical Waves

Mechanical waves require a medium to propagate and they depend on the elastic parameters of that medium. Therefore, Mechanical Waves (A) can be connected to 'Required a medium to propagate' (3) and 'Must be elastic parameters dependent' (4).
02

Analyze Electromagnetic Waves

Electromagnetic waves include light waves, microwaves etc. that can propagate through vacuum and do not need a medium. They are transverse in nature. Therefore, Electromagnetic Waves (B) correspond to 'Transverse only' (1).
03

Analyze Longitudinal Waves

In Longitudinal waves, the medium's displacement is parallel to the direction of wave propagation. They can exist as mechanical waves, so the properties will overlap with those of mechanical waves. Therefore, Longitudinal Waves (C) corresponds to 'Can be transverse or longitudinal' (2) and 'Required a medium to propagate' (3).
04

Analyze Pressure Waves

Pressure waves are a type of longitudinal wave where the medium's displacement is in the same or opposite direction to the wave's direction. Hence, Pressure Waves (D) are 'Longitudinal waves' and 'Required a medium to propagate' (3). They are also 'Must be elastic parameters dependent' (4).

A stationary source of sound is emitting waves of frequency \(30 \mathrm{~Hz}\) towards a stationary wall. There is an observer standing between the source and the wall. If the wind blows from the source to the wall with a speed \(30 \mathrm{~m} / \mathrm{s}\) then the number of beats heard by the observer is (velocity of sound with respect to wind is \(330 \mathrm{~m} / \mathrm{s})\) (A) 10 (B) 3 (C) 6 (D) Zero

A pipe of length \(85 \mathrm{~cm}\) is closed from one end. Find the number of possible natural oscillations of air column in the pipe whose frequencies lie below \(1250 \mathrm{~Hz}\). The velocity of sound in air is \(340 \mathrm{~m} / \mathrm{s}\) (A) 12 . (B) 8 (C) 6 (D) 4

A traveling wave pulse is given by \(y=\frac{6}{2+(x+3 t)^{2}}\), where symbols have their usual meanings, \(x, y\) are in metre and \(\mathrm{t}\) is in second. Then (A) The pulse is traveling along +ve \(x\)-axis with velocity \(3 \mathrm{~m} / \mathrm{s}\) (B) The pulse is traveling along -ve \(x\)-axis with velocity \(3 \mathrm{~m} / \mathrm{s}\). (C) The amplitude of the wave pulse is \(3 \mathrm{~m}\). (D) The pulse is a symmetric pulse.

Two pendulums of same amplitude but time period \(3 \mathrm{~s}\) and \(7 \mathrm{~s}\) start oscillating simultaneously from two opposite extreme positions. After how much time they will be in phase (A) \(\frac{21}{8} \mathrm{~s}\) (B) \(\frac{21}{4} \mathrm{~s}\) (C) \(\frac{21}{2} \mathrm{~s}\) (D) \(\frac{21}{10} \mathrm{~s}\)

The equation of a particle executing SHM is given by \(x=3 \cos \left(\frac{\pi}{2}\right) t \mathrm{~cm}\), where \(t\) is in second. The distance travelled by the particle in the first \(8.5 \mathrm{~s}\) is \(\left(24+\frac{n}{\sqrt{2}}\right)\) then the value of \(n\) is.
