Multiple choice physics study of sound types of waves sound as a wave of disturbance sound waves are longitudinal waves

Energy is not carried by 

  1. Transverse progressive waves

  2. Longitudinal progressive waves

  3. Stationary waves

  4. Electromagnetic waves
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

$Answer:-$ C option

All the propagating waves (wave on string -transverse , sound-longitudinal)  carry energy with them and also electromagnetic waves like light carry energy.
Stationary waves do not carry energy with them because their energy is confined in that area (as they are not propagating).

Multiple choice physics study of sound types of waves sound as a wave of disturbance sound waves are longitudinal waves

Waves inside a gas are

  1. Longitudinal

  2. Transverse

  3. Partly longitudinal, partly transverse.

  4. None of these
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

$Answer:-$ A option

In fluids (liquids and gases), atoms have no "equilibrium location"; they can move freely past each other. So if one atom gets moved by a disturbance, there's no restoring force to pull it back to its equilibrium location,
hence transverse waves cannot travel through fluids.
so only longitudinal waves can travel in gases and liquids.

Multiple choice physics study of sound types of waves sound as a wave of disturbance sound waves are longitudinal waves

The waves in which the particles of the medium vibrate in a direction perpendicular to the direction of wave motion is known as

  1. Longitudinal waves

  2. Propagated waves

  3. Transverse wave

  4. None of these
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Transverse waves have particles oscillating perpendicular to the direction of motion of wave. Ripple in the surface of water is transverse in nature

Multiple choice physics study of sound types of waves sound as a wave of disturbance sound waves are longitudinal waves

The waves which can propagate in metals are :

  1. longitudinal waves

  2. transverse waves

  3. both (a) and (b)

  4. neither (a) nor (b)
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Propagation of waves depends on the medium through which they propagate. Transverse wave need a medium rigid enough which neither liquid nor gas can provide and hence transverse wave can travel through metals. For longitudinal wave they just require a medium for propagation. Hence transverse and longitudinal wave can both propagate in metals.

Multiple choice physics study of sound types of waves sound as a wave of disturbance sound waves are longitudinal waves

Wave in which particles of the medium oscillate to and from about their mean position is

  1. Transverse wave

  2. Longitudinal wave

  3. Oscillatory wave

  4. None
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

By definition a wave in which the particles of the medium oscillate to and fro about their mean positions in the direction of propagation is known as longitudinal wave. It can be produced in any medium.

The waves in which the particles of the medium vibrate in a direction perpendicular to the direction of wave motion is known as

  1. Transverse wave

  2. Propagated waves

  3. Longitudinal waves

  4. Stationary waves

A Correct answer
Explanation

In transverse waves, particle of the medium vibrate in a direction perpendicular to the direction of wave motion.

When we pluck the wire of a sitar, the waves produced in the wire are

  1. Longitudinal

  2. Transverse

  3. Sometimes longitudinal and sometimes transverse

  4. Electromagnetic
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

A transverse wave is a moving wave that consists of oscillations occurring perpendicular (or right angled) to the direction of energy transfer. If a transverse wave is moving in the positive x-direction, its oscillations are in up and down directions that lie in the yz plane. In any pluck string instrument we are actually doing the same.

A transverse wave is a wave that consists of oscillations that are 

  1. parallel to the direction of wave propagation

  2. perpendicular to the direction of wave propagation

  3. radial to the direction of wave propagation

  4. none of the above

Transverse mechanical wave can travel in :

  1. Iron rod

  2. Hydrogen gas

  3. Water

  4. Stretched string

A,C,D Correct answer
Explanation

Transverse wave is that wave which vibrate the particles of medium in the medium in the $\bot $ar direction to the direction of wave propegation.

Exp :-    $\left( 1. \right) $ A wave on string.
             $\left( 2. \right) $ Ripples on water waves.
             $\left( 3. \right) $ EM wave.
             $\left( 4. \right) $ In metals like iron rod.

Multiple choice physics study of sound types of waves sound as a wave of disturbance sound waves are longitudinal waves

Choose the correct options for longitudinal wave

  1. maximum pressure variation is BAk

  2. maximum density variation is pAk

  3. pressure equation and density equation are in phase

  4. pressure equation and displacement equation are out of phase
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

In a longitudinal wave, the pressure variation and density variation are both proportional to the displacement gradient, causing them to be in phase with each other.

Multiple choice physics study of sound types of waves sound as a wave of disturbance sound waves are longitudinal waves

A longitudinal wave consists of :

  1. crest and trough in the medium

  2. compression and rarefraction in the medium

  3. both (a) & (b)

  4. nither (a) nor (b)
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

A longitudinal wave is characterized by the displacement of particles parallel to the direction of wave propagation, creating regions of compression and rarefaction. Crests and troughs are features of transverse waves.
