False. Waves do not carry the medium with them as they travel through it. Instead, they transfer energy through the medium without permanently displacing the particles of the medium.

False. Electromagnetic waves do not require a medium to travel; they can propagate through a vacuum.
False. The speed of a wave in a medium is determined by the properties of the medium itself, such as its density and elasticity, rather than the frequency of the wave. The frequency of a wave only affects its wavelength and energy, not the speed of the medium.
No, the world population actually increased during that period. It grew from around 1.8 billion in 1913 to approximately 2.5 billion by 1950.
False. Sound requires a medium, such as air, water, or a solid material, to travel through. In a vacuum where there is no medium, sound cannot travel.
False, They can use optical storage discs.
False. In general, the speed of sound increases as the temperature of a medium increases. This is because higher temperatures lead to greater molecular motion, which increases the speed at which sound waves can travel through the medium.
