Which physical quantity remain unchanged when light and sound passes through medium?
When light or sound pass through various media, their speed and wavelength change, but their frequencies remain constant.

Name the physical quantity which has the same value for the waves belonging to different em spectrum?
there is no need of medium to travel
In a guided medium signal passes through a physical pathway(s),while in an unguided medium signal passes through a vacuum,it is independent of a physical pathway.
Animals and man exhibit life through the physical medium of a brain. The brain serves as the coordinating center for all bodily processes.
Physical education is the systematic education to develop a man physically, mentally, emotionally, and socially through the medium of Physical Activity. Physical education is the systematic education to develop a man physically, mentally, emotionally, and socially through the medium of Physical Activity.
The frequency of the light remains unchanged as it depends on the source of the light rather than the medium its traveling in.
Sound energy is defined as the energy produced due to vibrating sound moving through a medium so it is a SCALAR quantity. Sound wave, on the other hand is a vector quantity.
What happen to the speed wavelength and frequency of a ray of light when it passes through a denser medium?
When light crosses the boundary from one medium into an optically denser one ... -- its speed decreases -- its wavelength increases -- its frequency is unchanged. As long as it stays in the denser medium, nothing changes, until it again crosses a boundary into a different medium.
The weight of an object depends on the object mass and the earth's gravity, and has nothing to do with the medium it is in. It is the definition of a physical quantity.
Physical education is the systematic education to develop a man physically, mentally, emotionally, and socially through the medium of Physical Activity.
YES IT IS. Any quantity which is ratio of two physical quantities having same unit is dimensionless. Dielectric constant is ratio of Permittivty of medium to the permittivity of free space. As Permittivity of medium and permittivity of free space both have same units(F/m ie Farad/meter) dielectric constant becomes dimensionless quantity
Travel through empty space without a physical medium.
A physical property of matter that can be produced by vibrations is called sound. Sound propagates through a medium such as air or water.
Flux is the presence of a force field in a specified physical medium, or the flow of energy through a surface.
A physical medium such as copper, fibre optic or air (wireless). e.g. Cat5 or Cat6 copper cable.
When a wave enters a different medium, its frequency remains unchanged, but its speed and therefore its wavelength both change.
Sound is a wave of compressions and must be propagated through a physical medium like air, water or metal.
Any wave that depends on a physical medium, such as a water wave or a sound wave.
Long Haul Handbag Quantity: 1 Weight: 13.2lbs Checked Luggage Quantity: 1 Weight: 50.6lbs Medium Haul Medium Haul Handbag Quantity: 1 Weight: 13.2lbs Checked Luggage Quantity: 1 Weight: 44lbs Short Haul Handbag Quantity: 1 Weight: 13.2lbs Checked Luggage Quantity: 1 Weight: 44lbs Checked luggage fees for excess weight are 1.6£/lb for long haul, 8£/lb for medium haul and 16£/lb for short haul.
As long as the medium through which the wave is traveling remains unchanged, the speed of the wave will not change, even if the amplitude and/or the frequency of the wave changes. Since the speed of a wave is a product of its frequency times its wavelength, for a given medium of propagation, when the frequency increases, the wavelength decreases and vice versa.
Physical media is a type of communication medium. Mostly thought in information technology classes
Which requires a physical medium in which to travel light, sound, or both?
Quantity of water in the air (or other medium surrounding the iron). Quantity of oxygen in the air (or other medium surrounding the iron). Additives to the iron during production. Surface area of the iron exposed. Chemicals in the air or other medium surrounding the iron that could catalyse the rusting process.
Both electrostatic fields and magnetic fields can influence objects in a vacuum, so EM waves (the combination of varying electromagnetic and electrostatic fields) have influence through a vacuum, that is, in the absence of a physical medium.
That depends on the density and other physical characteristics of the medium. In air at sea level, it's about 340 meters per second. In steel and rock, it can be in the neighborhood of 6,000 meters per second.
Seeming as the speed of sound in air speeds up if the temperature rises therefore how hot would you have to heat the air up until the speed of sound through that air is equal to the speed of light?
It never would. Sound is vibration through some physical medium; the speed of sound is related to the speed of the vibrations. No physical medium can move at the speed of light, so the speed of sound could never get there.
a medium. but longitudinal waves do not have to travel through a medium. This is why transverse waves cannot vibrate through space. a medium. but longitudinal waves do not have to travel through a medium. This is why transverse waves cannot vibrate through space.
False the wave goes through the medium only. And does not carry it.
No. Proof: There's no physical medium between the sun and earth. Light waves are different from sound waves, so light waves are able to travel without matter. That's why sound can't travel in space (a vacuum) but light can travel from the sun to earth through the vacuum of space.
the physical environment retains a central significance, as the medium with and through which human cultures act. His classic definition of a 'cultural landscape' reads as follows: "The cultural landscape is fashioned from a natural landscape by a cultural group. Culture is the agent, the natural are the medium, the cultural landscape is the result"
What is the reasoning that microwaves can travel through empty space as well as through air and food?
Microwaves are part of the electromagnetic spectrum, and as such they do not require any physical presence to aid passage, unlike sound waves which do require a medium through which to travel.
yes, a mechanical wave needs a medium to move through and a electromagnetic wave doesn't need a medium
Light or radioactive particles. They uses electro magnetic radiation as a medium for them to travel through, Waves like sound can not travel through vacuum because they need physical mediums like air.
The speed of sound through the medium also increases.
Sound wave. Any mechanical vibration requires a physical medium to travel through. All longitudinal, like earthquakes. Sound does not travel in space. A wave that travels through a vacuum is an Electromagnetic waves. ie it is a disturbance that propagates through space and time. EM waves vary in frequency producing light, infra-red, ultraviolet, radio waves etc... Sound waves are mechanical vibration through a medium, differing frequencies produce different pitches of sound.
the particles of the medium vibrate when sound waves passes through the medium.
Virtually any wave that is not EMR (electromagnetic radiation) requires a medium through which to move. Sound can move through air, water and many kinds of solid material, but it cannot move through vacuum. Light moves easily through vacuum (no medium) and in fact moves at its highest velocity in vacuum. Waves through a medium involve a rarefaction and compression of the material, and nothing physical actually moves across any great distance. Light is also… Read More
no light does not need a medium to travel through
We can always tell that a wave exists from the way some quantity changes in time and varies along the direction the wave is travelling in. So for a sound wave this quantity is air pressure, for a water wave it's the height of the water etc. For an EM wave it's the strength of the electric or magnetic fields. Whereas for the other two examples the quantity comes about from the existence of a… Read More
It's frequency is unchanged. A Light wave behaves (generally) according to v = fλ, where v is the speed at which the light wave travels, f is the frequency, and lambda (the upside-down y) is the wavelength. When medium is changed, wavelength is changed (think of a wave in a string - the particles are physically affected by the different density). Thus, to compensate for changing wavelength, the velocity will also change (inverse proportionality). And… Read More
Medium:It is the physical path overwhich the message travels from the sender to the receiver. Channel: physical transmission medium such as a wire, or to a logical connection over a multiplexed medium such as a radio channel.
Yes it is true, the state of a medium helps determine the speed of sound passing through the medium.
it is sound that requires a medium to travel .. light is an electromagnetic wave ..it doesn't require a medium..
Sound causes vibrations in waves that pass through a medium.
Air is the medium (if you are talking about something travelling through it).
the wave which does not travel through a medium is called electromagnetic wave.
when a wave travel through medium then sound is produced
The information would be your height, weight, and physical build.
It does not need a medium.
