Despite their extensive applications in communication systems, radio waves and microwaves are not the only form of EM waves present in our atmosphere. Another form of EM radiation plays an even more important role in our life (and the life of our planet): sunlight. The sun emits over a wide range of frequencies; however, the fraction of its radiation that reaches the earth's surface is mostly in the visible spectrum. (Note that about 35% of the radiation coming from the sun is absorbed directly by the atmosphere before even reaching the earth's surface.) The earth, then, absorbs this radiation and reemits it as infrared waves. Part C Based on this information, which of the following statements is correct? Check all that apply. ▸ View Available Hint(s) The earth absorbs visible light and emits radiation with a shorter wavelength. The earth absorbs visible light and emits radiation with a longer wavelength. The earth absorbs visible light and emits radiation with a lower frequency. The earth absorbs visible light and emits radiation with a higher frequency.

Question
![Electromagnetic radiation is more common than you might expect.
Radio and TV stations emit radio waves as they broadcast their
programs; microwaves cook your food in a microwave oven;
conventional ovens and stoves emit infrared and slightly visible
radiation; dentists use X rays to check your teeth; and cell phones
operate using microwaves as well, but at a lower frequency than
microwave ovens. Even though they have different names and different
applications, these types of radiation are really all the same thing:
electromagnetic (EM) waves - energy that travels in the form of
oscillating electric and magnetic fields.
The radiation emitted by some wireless local area networks has the shortest wavelength of all the technologies listed above.
All these technologies emit waves with a wavelength in the range 0.01 to 10.0 m.
All these technologies emit waves with a wavelength in the range 0.01 to 10.0 km.
