Electromagnetic waves are transverse waves. That means the electric and magnetic fields change (oscillate) in a plane that is perpendicular to the direction of propagation of the wave. Also note that electric and magnetic fields in an EM wave are also perpendicular to each other.
Are electromagnetic waves longitudinal yes or no?
Originally Answered: Are electromagnetic waves longitudinal or transverse? They are transverse. That means the wave oscillates in a direction perpendicular to the direction in which it travels.
Are electromagnetic waves transverse or longitudinal justify your answer?
Electromagnetic waves are transverse waves. Their vibrations or oscillations are changes in electrical and magnetic fields at right angles to the direction of wave travel.
Are electromagnetic waves transverse waves?
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.
Are electromagnetic waves both longitudinal and transverse?
Longitudinal waves occur when the oscillations are parallel to the direction of propagation. While mechanical waves can be both transverse and longitudinal, all electromagnetic waves are transverse.
Why electromagnetic waves are transverse?
Electromagnetic waves are also transverse waves because the direction of particle displacement is also perpendicular to the direction of movement, producing the waveform of visible light, and other types of electromagnetic radiation.
Why electromagnetic waves are transverse in nature?
When an electric field vector and magnetic field vector oscillate together, it forms a wave. … Due to the perpendicular directions of the electric and magnetic fields to each other and also to the direction of propagation of the wave, the electromagnetic wave is transverse in nature.
What is the difference between magnetic and electromagnetic waves?
Electromagnetic waves are caused by fluctuation of both electric and magnetic field. These are perpendicular to electric and magnetic waves. They travel in any medium. Magnetic field is like the area enclosing a magnetic substance where another magnetic substance is affected.
Which of the following is not an electromagnetic wave?
Sound wave is not an electromagnetic wave. It is a mechanical wave. When sound wave propagates, particles of the medium oscillates along the direction of propagation of the wave.
Which of the following are electromagnetic waves?
The correct answer is option 1 i.e Infrared rays. Waves that consist of vibrating electric and magnetic fields are called electromagnetic waves.
The examples of electromagnetic waves are:
- Radio waves.
- Infrared waves.
- Visible light.
- Gamma rays.
Which waves are longitudinal waves?
Examples of longitudinal waves include:
- sound waves.
- ultrasound waves.
- seismic P-waves.
What kind of wave is electromagnetic wave?
EM waves are ‘transverse’ waves. This means that they are measured by their amplitude (height) and wavelength (distance between the highest/lowest points of two consecutive waves). The highest point of a wave is known as ‘crest’, whereas the lowest point is known as ‘trough’.
What is longitudinal and transverse waves?
In a transverse wave, the particles are displaced perpendicular to the direction the wave travels. … In a longitudinal wave the particles are displaced parallel to the direction the wave travels. An example of longitudinal waves is compressions moving along a slinky.
Do electromagnetic waves require a medium?
Electromagnetic waves differ from mechanical waves in that they do not require a medium to propagate. This means that electromagnetic waves can travel not only through air and solid materials, but also through the vacuum of space.
Which of the following is not transverse wave?
The correct option is B sound waves travelling in air. Explanation:Sound waves travelling in air are longitudinal waves.
