A mixture of molten or semi-molten rock
hot molten or semifluid rock erupted from a volcano or fissure, or solid rock resulting from cooling of this
steep conical hill of loose pyroclastic fragments
conical volcano built up by many layers (strata) of hardened lava, tephra, pumice, and volcanic ash
a type of volcano usually built almost entirely of fluid magma flows
roughly circular mound-shaped protrusion resulting from the slow extrusion of viscous lava from a volcano
a bowl-shaped geological formation at the top of a volcano
a mountain that produces magma, lava, and ash and is formed by cracks in the Earth's surface
a giant, fast moving wave that is caused by an earthquake or volcano
For waves on the surface of the ocean or lakes
This article is about the scalar physical quantity
a measurement that indicates the movement or vibration of something (such as a sound wave or a radio wave)
Frequency is the number of occurrences of a repeating event per unit time
In physics, the wavelength of a sinusoidal wave is the spatial period of the wave—the distance over which the wave's shape repeats,
the lowest turning point of a wave cycle
A crest is a point on the wave where the displacement of the medium is at a maximum.
A transverse wave is a moving wave that consists of oscillations occurring perpendicular to the direction of energy transfer.
Longitudinal waves, also known as "l waves", are waves in which the displacement of the medium is in the same direction as, or the opposite direction to, the direction of travel of the wave.
the point or place where something begins or is created
Infrared (IR) is invisible radiant energy,
Radio waves are a type of electromagnetic radiation with wavelengths in the electromagnetic spectrum longer than infrared light.
Ultraviolet (UV) light is an electromagnetic radiation with a wavelength from 10 nm (30 PHz) to 380 nm (750 THz), shorter than that of visible light but longer than X-rays.
A gamma wave is a pattern of neural oscillation in humans with a frequency between 25 and 100 Hz, though 40 Hz is typical.
Visible light waves are the only electromagnetic waves we can see
Space void of matter.

EM waves with frequencies between microwaves and visible light
electromagnetic waves with the lowest frequencies
the range of all electromagnetic frequencies
a type of wave that does not require a medium to travel; a disturbance that transfers energy through a field
EM waves with frequencies above visible light and below x-rays
EM waves with frequencies between ultraviolet light and gamma rays
