What does trough of a wave mean?
The highest surface part of a wave is called the crest, and the lowest part is the trough. The vertical distance between the crest and the trough is the wave height. The horizontal distance between two adjacent crests or troughs is known as the wavelength.
What are the 7 electromagnetic waves and their uses?
Though the sciences generally classify EM waves into seven basic types, all are manifestations of the same phenomenon.
- Radio Waves: Instant Communication.
- Microwaves: Data and Heat.
- Infrared Waves: Invisible Heat.
- Visible Light Rays.
- Ultraviolet Waves: Energetic Light.
- X-rays: Penetrating Radiation.
- Gamma Rays: Nuclear Energy.
What are the classification of waves?
One way to categorize waves is on the basis of the direction of movement of the individual particles of the medium relative to the direction that the waves travel. Categorizing waves on this basis leads to three notable categories: transverse waves, longitudinal waves, and surface waves.
What are 3 examples of electromagnetic waves?
Radio waves, microwaves, visible light, and x rays are all examples of electromagnetic waves that differ from each other in wavelength.
Do all waves repeat?
Water waves exhibit characteristics common to all waves, such as amplitude, period, frequency and energy. The simplest waves repeat themselves for several cycles and are associated with simple harmonic motion.
What does throughout mean?
1 : in or to every part : everywhere of one color throughout. 2 : during the whole time or action : from beginning to end remained loyal throughout. Synonyms More Example Sentences Learn More about throughout.

What are the three properties of waves?
However, all waves have common properties—amplitude, wavelength, frequency, and speed. Amplitude describes how far the medium in a wave moves. Wavelength describes a wave’s length, and frequency describes how often it occurs. Speed describes how quickly a wave moves.
What are the 4 parts of a wave?
Wave: The repeating and periodic disturbance that travels through a medium (e.g. water) from one location to another location. Wave Crest: The highest part of a wave. Wave Trough: The lowest part of a wave. Wave Height: The vertical distance between the wave trough and the wave crest.
What is 1 cycle?
One cycle, specified event, is measured 1 second in time which equals 1 Hz. As the CWNA mentioned, “alternating current is defined as a single change from up to down to up, or as a change from positive, to negative to positive” Example 2 – (5) Cycles.
What are the harmful effects of electromagnetic waves?
Reported symptoms include headaches, anxiety, suicide and depression, nausea, fatigue and loss of libido. To date, scientific evidence does not support a link between these symptoms and exposure to electromagnetic fields.
How do we use electromagnetic waves in everyday life?
Everyday life is pervaded by artificially made electromagnetic radiation: food is heated in microwave ovens, airplanes are guided by radar waves, television sets receive electromagnetic waves transmitted by broadcasting stations, and infrared waves from heaters provide warmth.
What is a wave cycle?
Wave cycles are pairs of a maximum value and a corresponding minimum value. The crest front wavelength is the distance between the minimum and the maximum. A min2Max cycle is a pair of a local minimum and the following local maximum.
What are three examples of a medium?
An example of a medium is a metal spoon sitting in a cup of hot tea that is too hot to touch. An example of a medium is a newspaper from the combined media form of newspapers, television, magazines, radio and the Internet.

Here are some examples of normal ups and downs: It is typical for an individual to experience moments of sadness due to a traumatic event. It is also normal for these feelings to last several weeks, but not for them to completely change an individual’s life.
How often waves repeat is called their?
Frequency is a measurement of how often a recurring event such as a wave occurs in a measured amount of time. One completion of the repeating pattern is called a cycle.
