Wave Parts_Frequencies of waves
Waves
Definition: Waves are disturbances that transfer energy from one place to another without transferring matter.
Parts of Electromagnetic Waves
Wavelength: The distance between two consecutive crests or troughs in a wave. It is represented by the Greek letter lambda (λ).
Crest: The highest point of a wave.
Trough: The lowest point of a wave.
Amplitude: The maximum extent of a wave's displacement from its rest position. It indicates the wave's energy level.
Origin: The point through which the wave starts its propagation.
Time and Frequency
Time: The duration over which waves occur, crucial for determining frequency.
Frequency: Defined as the number of waves passing a point in a given period of time.
Unit: Hertz (Hz), equivalent to one cycle per second (1/sec).
Frequency Ranges
Low Frequency: Characterized by longer wavelengths and lower energy.
High Frequency: Features shorter wavelengths and higher energy.
Ultra-high Frequency: Even shorter wavelengths and the highest energy levels among radio waves.

Types of Electromagnetic Waves
Radio waves: Used for communication; have the longest wavelengths and lowest frequencies.
Microwaves: Used for cooking and radar technology; shorter wavelengths than radio waves.
Infrared waves: Felt as heat and used in thermal imaging; shorter wavelengths than microwaves.
Visible light: The part of the spectrum visible to the human eye; wavelengths range from approximately 400 nm (violet) to 700 nm (red).
Ultraviolet waves: Responsible for sunburn; higher energy than visible light.
X-rays: Used in medicine for imaging; have short wavelengths and high energy.
Gamma rays: The highest energy electromagnetic waves; produced by radioactive atoms and in nuclear explosions.

New Additions
Nuclear Fusion: A process where two light atomic nuclei combine to form a heavier nucleus, releasing energy in the process. This is the fundamental process that powers the sun and other stars.
Photons: The elementary particles of light and all other forms of electromagnetic radiation. Photons carry energy that is proportional to the radiation frequency and are responsible for the electromagnetic force in quantum mechanics.
