What is the difference between a mechanical wave and an electromagnetic wave? A mechanical wave travels through empty space, while an electromagnetic wave travels through matter.
A mechanical wave has a short wavelength, while all electromagnetic waves have long wavelengths.
A mechanical wave has a high frequency, while all electromagnetic waves have low frequencies.
A mechanical wave travels through matter, while an electromagnetic wave travels through empty space.

A  a mechanical wave travels through empty space, while an electromagnetic wave travels through matter.

Explanation: A mechanical wave travels through empty space, while an electromagnetic wave travels through matter. A mechanical wave has a short wavelength, while all electromagnetic waves have long wavelengths.

answera compound;

the answer is false. this is because for ice to melt, it requires latent heat of melting. latent heat means heat energy required to change phase without any increase in temperatures. therefore, the ice will take energy from the environment to melt hence atmospheric temperatures will reduce.
