Question

define : wavelength , wave number , frequency , amplitude , crust , trough

Answer 1

✴Wavelength=> The distance in the line of advance of a wave from any one point to the next point of corresponding.

✴Wave number=> The number of waves in a unit distance.

✴Frequency=> The number of waves that pass a fixed place in a given amount of time.

✴Amplitude=> The maximum displacement or distance moved by a point on a vibrating body or wave measured from its equilibrium.

✴Crust=> The outer layer of the Earth, between the surface and the mantle.

✴Trough=> An extended region of relatively low atmospheric pressure, often associated with fronts.

Answer 2

Here is your answer

Wavelength:The distance between two waves of energy.

Wave number:Wave number refers to the number of complete wave cycles of
an electromagnetic field

Frequency:The number of complete cycles per second in alternating current direction.

Amplitude:The maximum displacement or distance moved by a point on a vibrating body or wave measured from its equilibrium position.

Crest:A crest is the point on a wave with the maximum value of upward displacement within a cycle.


Trough:A trough is the opposite of a crest, so the minimum or lowest point in a cycle.
