Top best answers to the question «How do you describe a light wave»
When most people use the term light waves, they usually mean visible light. In physics however, the term light waves tends to be used as a synonym for electromagnetic waves… From lowest energy to highest energy (red to blue) there are radio waves, microwaves, infrared, visible light, ultraviolet, x-rays and gamma rays.
Those who are looking for an answer to the question «How do you describe a light wave?» often ask the following questions:
👋 Describe how light travels as a wave?
Light travels as waves. These are transverse waves, like the ripples in a tank of water. The direction of vibration in the waves is at 90° to the direction that the light travels. Light travels in straight lines, so if you have to represent a ray of light in a drawing, always use a ruler.

- Is wave height used to describe a wave?
👋 What characteristic describe a wave?
No matter whether you are talking about vibrations or waves, all of them can be characterized by the following four characteristics: amplitude, wavelength, frequency, and speed.
- Describe how a sound wave propagates?
- Describe how electromagnetic wave is produced?

👋 What properties describe electromagnetic wave?
Like other waves, electromagnetic waves have properties of speed, wavelength, and frequency.

What are sound waves and how do they work?
- Sound waves are like light and water waves in other ways too. When water waves traveling long distances across the ocean flow around a headland or into a bay, they spread out in circles like ripples. Sound waves do exactly the same thing, which is why we can hear around corners.
A movement of water cause by currents and wind.
- Sound is a longitudinal wave which consists of compressions and rarefactions travelling through a medium. Sound wave can be described by five characteristics: Wavelength, Amplitude, Time-Period, Frequency and Velocity or Speed.
- Definition: What are Mechanical Waves? Mechanical waves are produced when particles vibrate in a medium in which the wave propagates. As a result, momentum and energy are exchanged among the particles and between the particles and the medium. Mechanical waves can propagate through solid, liquid, or gas.
- sound wave. A sound wave is the pattern of disturbance caused by the movement of energy traveling through a medium (such as air, water, or any other liquid or solid matter) as it propagates away from the source of the sound. The source is some object that causes a vibration, such as a ringing telephone, or a person's vocal chords.

Different waves, same properties
A wave can be described by its length, height (amplitude) and frequency. All waves can be thought of as a disturbance that transfers energy. Some waves (water waves and sound waves) are formed through the vibration of particles.
Light waves are just one type of electromagnetic wave. Other electromagnetic waves include the microwaves in your oven, radio waves, and X-rays. Light waves are regarded as a varying electric field (E) coupled with a varying magnetic field (B), at right angles to each other and to the direction of travel.
Video answer: Gcse physics - intro to waves - longitudinal and transverse waves #61Describe how a standing wave is formed?
Standing waves are formed by the superposition of two travelling waves of the same frequency (with the same polarisation and the same amplitude) travelling in opposite directions. This is usually achieved by using a travelling wave and its reflection, which will ensure that the frequency is exactly the same.Describe how an electromagnetic wave is created?
- Electromagnetic radiation or electromagnetic waves are created due to periodic change of electric or magnetic field. Depending on how this periodic change occurs and the power generated, different wavelengths of electromagnetic spectrum are produced. In a vacuum, electromagnetic waves travel at the speed of light, commonly denoted c.
- P wave A P wave, or compressional wave, is a seismic body wave that shakes the ground back and forth in the same direction and the opposite direction as the direction the wave is moving.
Video answer: The equation of a wave | physics | khan academyHow do you describe a sine wave?
A sine wave is a geometric waveform that oscillates (moves up, down or side-to-side) periodically, and is defined by the function y = sin x. In other words, it is an s-shaped, smooth wave that oscillates above and below zero.How do you describe a sound wave?
Sound is a mechanical wave that results from the back and forth vibration of the particles of the medium through which the sound wave is moving… The motion of the particles is parallel (and anti-parallel) to the direction of the energy transport. This is what characterizes sound waves in air as longitudinal waves.How do you describe a transverse wave?
Transverse wave, motion in which all points on a wave oscillate along paths at right angles to the direction of the wave's advance. Surface ripples on water, seismic S (secondary) waves, and electromagnetic (e.g., radio and light) waves are examples of transverse waves.How would you describe a surface wave?
it occurs at the boundary of two different mediums, such as air and water.
- Transverse wave, motion in which all points on a wave oscillate along paths at right angles to the direction of the wave’s advance. Surface ripples on water, seismic S (secondary) waves, and electromagnetic ( e.g., radio and light) waves are examples of transverse waves. Waves come in two varieties.
Sound waves are often simplified to a description in terms of sinusoidal plane waves, which are characterized by these generic properties:
- Frequency, or its inverse, wavelength.
- Amplitude, sound pressure or Intensity.
- Speed of sound.
- The amplitude of a wave refers to the maximum amount of displacement of a particle on the medium from its rest position. In a sense, the amplitude is the distance from rest to crest. Similarly, the amplitude can be measured from the rest position to the trough position. A wave is a repeating pattern.
- Light Wave #1 will appear brighter than Light Wave #2. Light Wave #1 will be a different color than Light Wave #2. Light Wave #1 will reflect more easily than Light Wave #2. Light Wave #1 will travel in a straight line, but not Light Wave #2.

- Light is a very complex phenomenon, but in many situations its behavior can be understood with a simple model based on rays and wave fronts. A ray is a thin beam of light that travels in a straight line. A wave front is the line (not necessarily straight) or surface connecting all the light that left a source at the same time.
- Most of the time, light behaves as a wave and it is categorized as one of the electromagnetic waves because it is made of both electric and magnetic fields. Electromagnetic fields perpendicularly oscillate to the direction of wave travel and are perpendicular to each other. As a result of which, they are known as transverse waves.
