Question

Electromagnetic radiation is more common than you think. Radio and TV stations emit radio waves when they broadcast their programs; microwaves cook your food in a microwave oven; dentists use X rays to check your teeth. Even though they have different names and different applications, these types of radiation are really all the same thing: electromagnetic (EM) waves, that is, energy that travels in the form of oscillating electric and magnetic fields.

Part C
Based on this information, which of the following statements is correct?
Check all that apply.

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.

Explanation / Answer

Oops..sorry..I did a miscalculation there..it must be lower frequency..as wavelength is longer..hence b and C Earths absorbs more energy waves and emits less energy waves. energy is inversely prpoportional to wavelength. and wavelength is inversely proportional to frequency. hence answers will be.. b.The earth absorbs visible light and emits radiation with a longer wavelength. c.The earth absorbs visible light and emits radiation with a lower frequency.
