3 ghz to 300ghz
At microwave frequency, water molocules resonate, creating heat.
Microwave ovens operate at about 2,450 MHz.
The frequency can range between 300 MHz and 300 GHz.
The microwave energy in a microwave oven is of a much lower frequency than light, but light is electromagnetic energy like the microwave radiation is.
The frequency at which a microwave oven operates, about 2,450 MHz, has a wavelength of about 12 cm.

3ghz-300ghz
At microwave frequency, water molocules resonate, creating heat.
Microwave ovens operate at about 2,450 MHz.
"Microwave" radiation is any radio wave at frequencies between 3 GHz and 300 GHz. Microwave cooking ovens are licensed to operate at a certain definite frequency, just like any other radio transmitter is. For microwave ovens in the US, the frequency is 2.450 GHz.
The frequency can range between 300 MHz and 300 GHz.
UHF and microwave
If 'a' and 'b' are talking to each other, i.e. communicating, then Tx-a = Rx-b, and Tx-b = Rx-a.
at microwave frequency why should the transmission line may considered to be made of unit length?
The microwave energy in a microwave oven is of a much lower frequency than light, but light is electromagnetic energy like the microwave radiation is.
microwave
The "microwave" range of radio waves is defined as frequencies between 3 - 300 GHz. But the question says " a " microwave, so we suspect it's talking about the box you use to heat the leftover meat loaf. The microwave oven operates in the Industrial/Scientific/Medical frequency band, at or near 2,450 MHz. (So, technically, it isn't a 'microwave' at all, since that frequency is below the range defined as 'microwave'. Guess it should be called a "UHF Oven".)
