What is a wave?

Transverse wave:

A transverse wave consists of the trough which is the lowest point of the wave beneath the line of
origin. There is also the crest which is the highest point of the wave above the line of…

Sound as a longitudinal wave:

Sound waves are produced due to the vibrating of an object through the atoms which also causes the
air surrounding the object to vibrate. The wave lengths refract and compress which is the forming of
the vibration.

The frequency is another property of the sound wave and this
is the number of times the wavelength occurs in one second. This is usually measured in kilohertz
(KHz). The frequency can be seen as the faster the sound source vibrates, the higher…

Light as transverse waves:

Light is a transverse wave purely because
all electromagnetic radiation, including visible light, is transverse waves. In transverse the waves are
seen to be vibrating at right angles to the direction of travel.

The basic properties of transverse waves…

Describe the electromagnetic spectrum:

The electromagnetic
spectrum is the range of all possible electromagnetic radiation, such as radio, microwave, infrared,
light, x-rays and gamma rays. The differences between the rays are determined through the length
and style of the waves. A few examples…
