A is wrong.
B is right
C is right
D is wrong
A: Sound travels as a wave, therefore it does not travel in a straight line.
B: Sound travels in a wave.
C: The sound wave is a form of energy; all waves are.
D: Sound cannot travel in a vaccuum. A is not entirely wrong.
steel
It travels faster in a vacuum.
it travels faster through air.
Light travels fastest through vacuum.
Energy. Light and radio waves etc.
Sound energy travels in linear formation. It travels through a medium like solid or through the air. In space sound does not travel because there is a vacuum.
light travels faster in vacuum.
It travels faster in a vacuum.
It travels fastest in a vacuum.
No
No
Energy from the sun travels through the vacuum of space by radiation.
it travels faster through air.
Light travels fastest through vacuum.
Light travels faster (up to the speed of light) in a vacuum, which is empty space. Light travels slower through a medium (matter).
Energy. Light and radio waves etc.
Sound travels faster through a solid than through a vacuum. In a solid, sound waves propagate through the material's molecules, leading to faster transmission. In a vacuum, there are no molecules to transmit sound, so it cannot travel at all.
In free space in a vacuum, EM energy travels at 300,000 km/sec
