Sound waves in air are:
RRB Group-D
02/11/2018 (Shift-III)
2018
✓ Answer:CLongitudinal
Air particles oscillate parallel to the direction of sound propagation.
112
Why cannot sound be heard through the surroundings on the Moon?
RRB JE

2019
✓ Answer:CThere is no substantial atmosphere, and sound requires a medium
Sound needs a material medium. The Moon's near-vacuum does not support ordinary airborne sound propagation.
113
Sound waves travel at:
RRB Group-D
02/11/2018 (Shift-II)
2018
✓ Answer:ADifferent speeds in different media
Sound speed depends on the medium's elastic properties, density and conditions such as temperature.
114
Through which medium can sound NOT travel?
RRB NTPC (Stage-I)
