Andre listed some properties of electromagnetic waves. 1) transfer thermal energy by radiation
2) can transfer energy over great distances
3) need matter to transfer energy through
4) are disturbances that carry energy
Which best describes Andre’s error?
Electromagnetic waves transfer thermal energy by conduction.
Electromagnetic waves can only transfer energy over short distances.
Electromagnetic waves can transfer energy through empty space.
Electromagnetic waves are not considered disturbances.

Electromagnetic waves can transfer energy through empty space.

Explanation:

Electromagnetic waves are formed when an electric field comes in contact with a magnetic field. The electric field and magnetic field of an electromagnetic wave are perpendicular to each other. They are also perpendicular to the direction of the wave.

Electromagnetic waves travel with speed of light in vacuum.

Electromagnetic wave does not need a medium to propagate or travel from one place to another. Electromagnetic waves are 'transverse' waves which means that they are measured by their amplitude and wavelength.

Electromagnetic waves do not lose energy when they travel and thus can travel far from its source.

as a general rule, scissors have blades less than 6 in (15 cm) long and usually have handles with finger holes of the same size. shears have blades scissors used to cut hair or fabric must be much sharper.
