Respuesta :
The chocolate softens and melts as it absorbs the microwaves, and it makes a mess.
Answer: Option (b) is the correct answer.
Explanation:
A radar emits microwaves which have longer wavelengths and a frequency range of 1 GHz to 300 GHz.
The microwaves are like electromagnetic waves and produces heat due to the emission of radiation.
Thus, when a chocolate bar is placed near a working radar set that is used to locate ships and airplanes then the chocolate bar will softens and melts as it absorbs microwaves from the radar set.
