Question

Microwaves are used in ovens to heat food has a frequency range of 300 MHz to 300 GHz. One should use porcelain vessels and not metal containers in a microwave. What reasons you should make to support it? How can you find out the range of energy associated with these microwaves? Can you identify the wave in electromagnetic spectrum which has energy 6.6 X10-27J ? Find out the common practical use of this EM wave and microwaves. What will be the ratio of its speed in air? [Given: Planck’s constant, h= 6.626x10-34 J.s and speed of light, C = 3 x 108 m/s.]
