Webb4 feb. 2024 · (c) Microwaves are heat waves, so always produce heating. (d) Infrared waves produce heating in a microwave oven. Answer Answer: (a) When frequency of microwave matches with frequency of water molecules i.e., resonant condition. Maximum energy is transferred to water molecules as their K.E. energy. Q.17. WebbThe subject of microwave and infrared properties of semiconductors is vast. A large impetus was given in 1955 with the ‘birth’ of magneto-optics semi- conductors brought on by the measurement of microwave cyclotron resonance in Ge and Si (Lax et al. 1954, Dresselhaus et al. 1955 a). This was followed by a host
