Waves And Their Types by Vishwa Vijayasankar #528
Mechanical Waves
A disturbance in matter that carries energy from one place to another.
Vibration travels through medium
The properties of mechanical waves are their period, frequency, wavelength, speed, and amplitude.
Transverse Waves
A wave that oscillates perpendicular to the axis along which the wave travels.
The medium vibrates in a direction perpendicular to the direction in which the wave travels.
Frequency is 1.0 hertz vibrating at one cycle per second.
The wavelength is long.
Longitudinal Waves
A wave in which the vibration of the medium is parallel to the direction the wave travels
Frequency is 2.0 hertz vibrating at two cycles per second
The wavelength is short.
Surface Waves
A wave that travels along a surface separating two media
The vibration is perpendicular to the direction in which the wave travels
Frequency is 1.0 hertz vibrating at one cycle per second
The wavelength is long
Electromagnetic Waves
One of the waves that are propagated by simultaneous periodic variations of electric and magnetic field intensity
Types of Electromagnetic Waves: Radio waves, microwaves, infrared, visible lights, ultraviolet, x-rays, and gamma rays.
Difference between Electromagnetic waves and Mechanical waves: Electromagnetic waves are produced by the vibration of the charged particles, but mechanical waves require a medium in order to transport energy from one place to another
