What determines if an
The physical quantity that determines if an electromagnetic wave emitted from an object is a visible light wave or an infrared light wave.
Answer to Problem 1CQ
The frequency of the wave determines the emitted wave as visible or infrared light.
Explanation of Solution
Whenever a charged particle is accelerated by some external force, electromagnetic waves are formed. These waves consist of electric and magnetic fields and become separated from the charged particle.
The frequency of the electromagnetic waves is directly depends on the acceleration of the charged particle. It means frequency of the electromagnetic wave is higher for the higher acceleration. The spectrum of the electromagnetic waves ranges from low frequency radio waves to the high frequency gamma rays.
Conclusion:
Therefore, the frequency of the wave determines the emitted wave as visible or infrared light.

Model the electromagnetic wave in a microwave oven as a plane traveling wave moving to the left, with an intensity of 25.0 kW/m2. An oven contains two cubical containers of small mass, each full of water. One has an edge length of 6.00 cm, and the other, 12.0 cm. Energy falls perpendicularly on one face of each container. The water in the smaller container absorbs 70.0% of the energy that falls on it. The water in the larger container absorbs 91.0%. That is, the fraction 0.300 of the incoming microwave energy passes through a 6.00-cm thickness of water, and the fraction (0.300)(0.300) = 0.090 passes through a 12.0-cm thickness.
