WebVerified answer. physics. By applying Newton's laws to the oscillations of a continuous medium, one can show that the speed of a sound wave is given by c_ {s}=\sqrt {\frac {B} {\rho}}, cs = ρB, where \rho ρ is the density of the medium (mass per unit volume) and B is the bulk modulus, a measure of the medium's stiffness. WebSolution Verified by Toppr Correct option is A) Microwave ovens operate at a frequency of 2.45 GHz and this is NOT the resonant frequency of a water molecule. This frequency is much lower than the diatomic molecule resonant frequencies mentioned earlier.

Why can

WebThe usual operating frequency of a microwave oven is far below the resonant frequency of water vapor... and liquid water doesn't have a resonant frequency. The peak is 10GHz to 50GHz depending on temperature, while microwave ovens run at 2.4GHz or 0.9GHz. Also, the radio energy in a microwave oven can heat many other substances besides H2O.

Web3 dec. 2013 · A microwave oven heats water because the microwave radiation interacts with the dipole (separated positive and negative charge) of the water molecule . The microwaves turn the water molecules back and forth at approximately the frequency of the microwaves, imparting energy to them. WebI think the key words in the OP's title are "resonance [sic] frequency". Water would heat up regardless of what frequency is chosen. 2.4 GHz is a common operating frequency for household microwave ovens, but that's just because that's within an ISM band. Some professional microwave ovens operate at lower frequencies, although I'm not sure why.
