Answer 1

The main advantage of microwave is that it is a. Highly directive.

• We can directly control the power in a microwave as we can set a timer in it.
• The microwave also do not retain heat and hence by using them all of the kitchen does not gets heated up.
• At microwave frequencies, the directive properties gets better.
• As the frequency increases, the wavelength decreases.
