The correct answers to fill into the blank spaces are;

<h3>What is wave?</h3>

Wave is a periodic <u>disturbance</u> that moves away from a source which carries <u>energy</u> with it. Waves can be typified according to the <u>direction</u> of motion of the vibrating particles with respect to the direction in which the waves travel and according to <u>medium</u> .

<u>Longitudinal</u> waves vibrate perpendicularly to the direction in which the waves travel. This wave exhibits up and down motion. Longitudinal waves vibrate <u>perpendicular</u> or back and forth to the direction in which the waves travel.

<u>Electromagnetic</u> waves are combination of transverse and longitudinal waves. These move in a circular pattern as the waves pass by.

<u>Mechanical</u> waves need solid, liquid and gas medium to propagate or travel. Transverse, mechanical and surface waves are examples of mechanical waves.

Electromagnetic waves do not need <u>medium</u> to propagate. Radio waves, ultraviolet, infrared, and gamma rays are examples of <u>electromagnetic</u> waves. The nature of waves can be described through its terms, quantities and <u>propagation</u>.

The <u>crust</u> and trough refer to the highest point and lowest point of a wave pattern, respectively. The <u>magnitude</u> of a transverse wave is the maximum displacement of a particle of the medium on either side of its normal position when the wave passes. The frequency of periodic waves is the number of waves that pass a particular point for every one second while the <u>Amplitude</u> is the distance between adjacent crests or troughs.

The period is the time required for one complete wave to pass a particular point. The <u>speed</u> of the wave refers to the distance the wave travels per unit time. It is related to the frequency of the wave and wavelength through the following equation: wave speed= frequency x wavelength.
