Because there is no matter.

Front

What is true about the speed of radio waves compared to light waves?

Back

They have less energy & frequency, but still the SAME speed as the speed of light (300,000,000 m/s).

Front

What does Low Amplitude represent?

Back

Quieter Sounds.

Front

What property of the wave is represented by the letter 'B'?

Back

Amplitude.

Front

What is the definition of a wave?

Back

A disturbance that transfers energy through space or matter.

Front

What is the relationship between wavelength and frequency?

Back

They are inversely related; as wavelength increases, frequency decreases.

Front
