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

Water waves are

  1. longitudinal

  2. transverse

  3. neither longitudinal nor transverse

  4. both longitudinal and transverse
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Water waves are both longitudinal and transverse. As a wave travels throught he water, the particles travel in clockwise circles. The radius of the circles decreases as the depth into the water.

Hence option (D) is correct.

In a slinky

  1. Both transverse pulse as well as longitudinal pulse can be generated

  2. Both types of pulse cannot be generated

  3. Only a transverse pulse can be generated

  4. Only a longitudinal pulse can be generated
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Slinky is a dress which is tight-fitting, elastic and flexible. By fixing one end on a rigid support and holding the other end waves can be generated. By moving it back and forth, longitudinal waves can be generated. By moving up and down, transverse can be made.

Waves on water surface are

  1. Longitudinal

  2. Transverse

  3. Combination of longitudinal and transverse

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

Water surface exhibits a combination of both longitudinal and transverse waves. When the wave travels through the water, the particles travel in a circular path, both parallel and perpendicular to the direction of wave propagation.

When you speak to your friend, the quantity having a non unique value in the sound produced is

  1. amplitude

  2. wave velocity

  3. frequency

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

Amplitude and frequency depend on source and as frequency is different, wavelength also has to be different to maintain same speed as speed is constant for a medium in a particular condition.

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

Velocity of a transverse wave along a stretched string is proportional to ___________. (T=tension in the string).

  1. $\sqrt{T}$
  2. $\displaystyle T$
  3. $\displaystyle\frac{1}{\sqrt T}$
  4. $\displaystyle\frac{1}{T}$
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Velocity of transverse wave $v =\sqrt{\dfrac{T}{\mu}}$

where $T$ is the tension in the string and $\mu$ is the mass of string per unit its length.
$\implies$ $v \propto \sqrt{T}$

All waves can be classified into two categories which are

  1. Sound waves and electromagnetic waves

  2. Transverse waves and electromagnetic waves

  3. Longitudinal waves and electromagnetic waves

  4. Transverse waves and longitudinal waves
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

All waves can be classified into two categories . They are Transverse and longitudinal waves

A transverse wave is a wave in which particles of the medium move in a direction perpendicular to the direction that the wave moves.
A longitudinal wave is a wave in which particles of the medium move in a direction parallel to the direction that the wave moves
Therefore option $D$ is correct

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

Transverse nature of light was confirmed by the phenomenon of the

  1. refraction of light

  2. diffraction of light

  3. dispersion of light

  4. polarization of light.
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

The phenomenon of polarization confirms that light is a transverse wave because for polarization, the light should have different components oscillating in the different planes and a transverse wave has the oscillations perpendicular to the direction of propagation of the wave.

Chronometer is?

  1. An clock for determining the longitude of a vessel at sea

  2. An instrument for changing or reversing the direction of electric current

  3. An instrument for measuring the direction and velocity of wind

  4. An instrument for comparing intensities of colours
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Chronometer is an instrument for measuring time accurately in spite of motion or variations in temperature, humidity, and air pressure.So it can be used a a clock for determining the longitude of a vessel at sea.
