GENERAL KNOWLEDGE

Detailed explanation-1: -’Wave’ is a common term for a number of different ways in which energy is transferred: In electromagnetic waves, energy is transferred through vibrations of electric and magnetic fields. In sound waves, energy is transferred through vibration of air particles or particles of a solid through which the sound travels.

Detailed explanation-2: -It is important to remember that all waves transfer energy but they do not transfer matter . For example, if a ball is placed on the surface of a pond when ripples move across it, the ball will move up and down but not outwards with the wave.

Detailed explanation-3: -Waves can be either mechanical that transport mechanical, or kinetic, energy, or they can be electromagnetic that transport light and heat energy. When waves transfer energy, particles move perpendicular to the movement of the waves. Waves are measured using amplitude, wavelength, and frequency.

Detailed explanation-4: -Radiation is the transfer of heat energy through space by electromagnetic radiation. Electromagnetic radiation is made of waves of different frequencies.
