Answer :
Answer:
The speed of sound depends on the medium thru which it travels in contrast to light (electromagnetic) which can travel thru a vacuum.
The speed of sound will depend on the density of the air thru which it travels - the density of air is particularly affected by
humidity - water vapor in the air contributes to less density
temperature - warmer is less dense
motion of air - if the air is not motionless the speed will be affected
