True.
False. Radio waves are electromagnetic vibrations, while sound waves are mechanical vibrations.
Light waves are transverse. Sound waves are longitudinal ones. This is true no matter what grade you're in, and it'll still be true next year.
Speed = frequency x wavelengthThis is true for all waves, sound waves as well as electromagnetic waves.

Sound waves
False. Radio waves are electromagnetic vibrations, while sound waves are mechanical vibrations.
true
yes it is true for all waves.
Light waves are transverse. Sound waves are longitudinal ones. This is true no matter what grade you're in, and it'll still be true next year.
Electromagnetic waves can travel through empty space.
Speed = frequency x wavelengthThis is true for all waves, sound waves as well as electromagnetic waves.
it the ear canal
No. Those phenomena are characteristic of longitudinal waves, such as for example sound waves.
Sound waves at frequencies lower than humans can hear.
