2)WHAT IS MEAN BY EMW?
3)WHAT IS ELETROMAGNTIC FLEID?

Answer 1

Answer:

1. Nanotechnology is the term given to those areas of science and engineering where phenomena that take place at dimensions in the nanometre scale are utilised in the design, characterisation, production and application of materials, structures, devices and systems.
2. Definition of 'Electromagnetic Waves' Definition: Electromagnetic waves or EM waves are waves that are created as a result of vibrations between an electric field and a magnetic field. In other words, EM waves are composed of oscillating magnetic and electric fields.
3. An electromagnetic field is a classical field produced by accelerating electric charges. It is the field described by classical electrodynamics and is the classical counterpart to the quantized electromagnetic field tensor in quantum electrodynamics.
