Question

Visible light. X-rays and microwaves are all components of the electromagnetic spectrum
Which statement about the waves is correct?

Answer 1

Answer:

Infrared is in the range of the EM spectrum between microwaves and visible light. IR has frequencies from about 30 THz up to about 400 THz and wavelengths of about 100 μm (0.004 inches) to 740 nanometers (nm), or 0.00003 inches.12-Mar-2015

Answer 2

Visible light. X-rays and microwaves are all components of the electromagnetic spectrum.

The statement which is correct about waves is In a vacuum, microwaves travel faster than visible light and have shorter distances.

Explanation for the answer:

• Microwaves are the waves which radiate electromagnetic energy with shorter wavelengths.
• It is not reflected by the Ionosphere.
• not reflected by the Ionosphere.These waves travel in a straight line and are reflected through the conducting surfaces.
• These waves are easily attenuated within shorter distances.
• Thus, the correct sentence is In a vacuum, microwaves travel faster than visible light and have shorter distances.
