Question

Which of the following statements is correct about waves?
a) A wave that causes the elements of the medium to move perpendicular to the
direction of movement of the wave is a longitudinal wave.
b) A wave that causes the elements of the medium to move parallel to the
direction of movement of the wave is a transverse wave.
c) Both sound waves and light waves are longitudinal waves.
d) Sound waves are longitudinal waves whereas light waves are transverse waves.

Answer 1

Answer:

from my side answer is C.

I Hope it help you

please make as brain list

Answer 2

Statement (d) is the correct statement about waves.

• A longitudinal wave is a wave in which particles oscillate parallel to the direction of motion.
• A transverse wave is a wave in which particles oscillate perpendicular to the direction of motion.
• In sound wave propagation the particles of medium oscillate back and forth along the direction of propagation.
• In light waves, the electromagnetic fields oscillate perpendicular to the direction of propagation.
• Hence, sound waves are longitudinal waves whereas light waves are transverse waves.
