What is the angle between plane of vibration and plane of polarisation in plane polarised electromagnetic wave?
The angle between the plane of vibration and the plane of polarization in a plane-polarized electromagnetic wave is 90 degrees. The plane of vibration represents the direction of the electric or magnetic field oscillations, while the plane of polarization is the direction in which these fields propagate. Perpendicular alignment between these two planes ensures the wave remains plane-polarized.

How can electromagnetic waves become polarised?
Electromagnetic waves become polarized when their electric field vectors oscillate in a specific orientation, either vertically, horizontally, or at some angle in between. This can happen when the waves encounter certain materials or pass through specific filters that selectively allow vibrations in particular planes. Polarization filters are commonly used to block certain orientations of electric fields, resulting in the polarized electromagnetic wave.
What is the difference between mechanical waves and electromagnetic waves?
Mechanical waves require a medium to travel through, such as air or water, while electromagnetic waves can travel through a vacuum. Mechanical waves involve the vibration of particles in the medium, while electromagnetic waves consist of oscillating electric and magnetic fields.
What are the similarities and differences between mechanical and electromagnetic waves?
Mechanical waves and electromagnetic waves are both forms of energy that travel through a medium. However, mechanical waves require a medium to propagate, while electromagnetic waves can travel through a vacuum. Additionally, mechanical waves involve the vibration of particles in the medium, while electromagnetic waves consist of oscillating electric and magnetic fields.
What are the differences between electromagnetic waves and mechanical waves?
Electromagnetic waves do not require a medium to travel through, while mechanical waves do. Electromagnetic waves can travel through a vacuum, such as in space, while mechanical waves need a medium, like air or water, to propagate. Additionally, electromagnetic waves consist of oscillating electric and magnetic fields, while mechanical waves involve the vibration of particles in the medium they are traveling through.
How does electromagnetic (em) radiation travels through each state of matter?
Electromagnetic radiation can travel through air, solids, liquids, and gases. In solids and liquids, it generally moves through the atoms and molecules via vibration and interactions with the charged particles. In air and gases, it propagates through the space between molecules. The speed of electromagnetic radiation can vary depending on the medium it is traveling through, with the speed being fastest in a vacuum.

Is there any difference between polarisation and polarization?
Only the spelling, they are two spellings for the same thing.

What is the definition of periods in science?
The interval of time between successive occurrences of the same state in an oscillatory or cyclic phenomenon, such as a mechanical vibration, an alternating current, a variable star, or an electromagnetic wave.

Difference between monochromatic and polarized light?
Monochromatic means that it has only frequency. Polarized is definition for light which has its electric and magnetic vectors oscillating in a certain way (linearly polarized, elliptically and so on) but it might have many frequencies included. In the same time monochromatic light can be polarized.

WHAT IS THE Relationship between vibration and sound signals in telephone system?
sound is made from vibration
What is the difference between hertz and frequency in hearing?
Hertz and Frequency are the same thing = cycles-per-second. When used for the vibration of something .. like an electromagnetic sine-wave . . . then if that sine-wave is vibrating with a frequency between 20 Hz and 20,000 Hz, the human ear can "hear" it. If an electromagnetic wave vibrated much faster .. around 10^^15 Hz, then you'd be able to SEE it.
How does the vibration of particles change as the temperature moves between freezing and boiling?
The vibration of particles increase with the temperature.
What is relation between light and electromagnetic waves?
Light is an electromagnetic wave.
What is the difference between spontaneous emission of radiation and stimulated emission of radiation?
The laser causes the stimulated emission of radiation. The light emitted is monochromatic and coherent,that is plane polarised. I imagine that spontaneous emission occurs in a Light emitting diode ,monochromatic but not polarised. Hope this is of help
