(i) Sound propagates faster in steel than in air.
(ii) Sounds are produced through vibrations.
(ii) Sound propagates faster than light.
(iv) Sound does not require a medium for its propagation. which of the statements are correct.

b) 1 and 3
c) 1 and 2

answer fast I will mark u as the brainliest​

Answer 1

Answer:

c) is correct option

Explanation:

1. sound travels faster in steel as there atoms are more close to each other and travel fast
2. sound can't travel in vaccum medium

Answer 2

Answer:

c) 1 and 2

Explanation:

Sound waves require medium to travel . They travel through vibrations in the molecules of the particular medium. Since the molecules of solid are very tightly packed it is easier for the sound to propagate.

Sound is not faster than light and it do require a medium for propagation so the option iii and iv are not correct...
