Interpretation : The radio waves that could be used for cooking are to be predicted and explained.
Concept Introduction : A wide range of wavelengths of radiation makes up the
Answer to Problem 75A
Radio waves are not used for cooking due to their lower energy and frequency.
Explanation of Solution
Electromagnetic radiations come in a wide variety with varying frequencies and/or wavelengths.
The range of infrared region in the electromagnetic radiation is
The range of microwave region is
The range of radio wave region is
The frequency is directly proportional to the energy according to Planck’s equation.
The energy of microwave is higher than radio wave.
So, the radio waves have lower energy and it is not suitable for cooking.
