List the characteristics properties of all waves. at what speed do electromagnetic waves travel in a vacuum

Electromagnetic waves travel at  in vacuum

The fundamental properties that can be attributed to waves are;

reflectionrefractiondiffraction interference.

Other properties are ;

wavelengthfrequencyamplitude. A waves can be regarded as one that  disturb the  transfers energy.what all this electromagnetic waves has in common is their ability of them to travel in the vacuum with the same speed.Their speed in the vacuum is  300,000,000 metres per second which is the speed of light.

Electromagnetic radiation can be regarded as radiation that has waves of the electromagnetic field, which propagate   through the space, and it moves along with electromagnetic radiant energy.

Electromagnetic waves that are part of electromagnetic spectrum are: radio waves microwavesinfrared lightultravioletX-rays, gamma rays.Wavelength can be regarded as  distance that exist  between identical points i.e the adjacent crests of the  adjacent cycles in that waveform Frequency can be explained as the rate of vibration of the wave electromagnetic field per seconds.The amplitude of wave can be regarded as distance from the centre line to the bottom of a trough, or to the top of a crest.

Therefore, electromagnetic waves travel at 300,000,000 metres per second in vacuum.

  concave means having an outline or surface that curves inward like the interior of a circle or sphere. so the mirror curves inward.
