Light waves are
transverse
but sound waves are waves on strings are longitudinal.
Which of the following statement is correct light waves?
Light waves are
transverse
but sound waves are waves on strings are longitudinal.
Which of the following statements is correct about sound waves?
The correct answer is
Sound waves are longitudinal
and light waves are transverse. Require a medium. Travel with a speed of 332 m/s at 0
o
C.
Which statement about sound waves is true?
TRUE –
A sound wave transports its energy by means of particle interaction
. A sound wave cannot travel through a vacuum. This makes sound a mechanical wave.
Which of the following statement is not correct about the longitudinal waves?
As sound waves are longitudinal waves, the air particles vibrate to and fro in the direction of propagation of sound. Therefore option 2 is
incorrect
and option 3 is correct.
Which waves can be polarized?
Transverse waves that exhibit polarization include electromagnetic waves such as light and radio waves, gravitational waves, and
transverse sound waves
(shear waves) in solids.
Which of the following statement is correct both sound and light?
Correct option c the
sound waves in air are longitudinal
while the light waves are transverseExplanation:Light waves are electromagnetic waves. Light waves are transverse in nature and do not require a medium to travel hence they can travel in vacuum. Sound waves are longitudinal waves and require a medium to travel.
What is the correct statement of sound?
Sound is a mechanical wave and light is an electromagnetic wave. Thus sound
needs a medium to travel
. But light does not need a medium to travel. Sound is produced by the to and fro motion or the vibrations produced in an object, these vibrations propagate through the medium to finally reach the receiver.
Does light travel in a straight line?
Any physics student knows that light travels in a straight line
. … When light rays pass from air into water, for instance, they take a sharp turn; that’s why a stick dipped in a pond appears to tilt toward the surface. Out in space, light rays passing near very massive objects such as stars are seen to travel in curves.
What type of wave is a sound wave?
These particle-to-particle, mechanical vibrations of sound conductance qualify sound waves as
mechanical waves
. Sound energy, or energy associated with the vibrations created by a vibrating source, requires a medium to travel, which makes sound energy a mechanical wave.
What is the frequency of a wave?
Frequency, in physics,
the number of waves that pass a fixed point in unit time
; also, the number of cycles or vibrations undergone during one unit of time by a body in periodic motion.
Can sound waves be reflected?
Sound waves and light waves
reflect from surfaces
. The angle of incidence equals the angle of reflection .
Can sound waves travel through solid?
Sound travels more quickly through solids
than through liquids and gases because the molecules of a solid are closer together and, therefore, can transmit the vibrations (energy) faster. Sound travels most slowly through gases because the molecules of a gas are farthest apart.
Which of the following statement is wrong about sound wave?
Since there is no medium in vacuum, sound will not travel in vacuum and hence the
speed of sound in vacuum
will not be greater than the speed of sound in air. Therefore the fourth statement is wrong. So, the correct answer is “Option D”.
How are longitudinal waves made?
A longitudinal wave can be created in a slinky if
the slinky is stretched out in a horizontal direction and the first coils of the slinky are vibrated horizontally
. In such a case, each individual coil of the medium is set into vibrational motion in directions parallel to the direction that the energy is transported.
Which one of the following statement is not correct regarding the travel of sound waves?
Sound is a mechanical wave and needs a material medium like air, water, steel, etc. for its propagation. It
cannot travel through a vacuum
. Therefore option 4 is incorrect.
