The answer for this question is A. The layers are orignally horizontal
Answer a) is incorrect as sound does not travel in a vacuum.
Answer: D.ultraviolet rays, visible light, infrared radiation, microwaves.
Explanation:
Shorter wavelength means higher frequency and higher energy.
Thus, the correct sequence of electromagnetic waves from shorter wavelength to longer wavelength is:
D.ultraviolet rays, visible light, infrared radiation, microwaves.
<u>Ultraviolet rays have shorter wavelength (about 380 nm) and high energy. </u>
<u>Visible light has wavelength: 380 nm to 700 nm</u>
<u>Infrared wavelength: 700 nm to 1 mm</u>
<u>Microwave wavelength: 1 mm to 1 m</u>
Pseudoscience because it involves beliefs not facts
D. All of the above.
These are all places you could get information from, therefore making them all sources.
