Question

Microwave and ultrasonic radiation in green synthesis

Answer 1

Pressure and temperature are important parameters in reaction processes in chemical systems. However, it is a less well-known fact that other thermally initiated reactions can lead to sustainable results. The basic requirement is to capture the energy required by a reaction. Not only the energy required for the synthesis, but also that required for cooling are of interest here.

Answer 2

• Microwaves are electromagnetic radiations with wavelengths between (10-³) and (10-1).

• Micowaves cause water and fat molecules to vibrate so they are helpful in microwave cooking ovens.

• They are used in mobile phones and WIFI.

• They find place in radars also which is essential in ships, aircraft and weather forecasters to send signals
