When light travels from air to glass the wave speed decreases B'coz glass is denser than air.?
Correct.
Energy that travels at speed of light?
That can be light, or some other electromagnetic wave (light is an electromagnetic wave), or gravitational waves.
Is sound the fastest speed possible?
No!...Speed of light is the fastest speed possible, but now a new particle called lepton is more faster than light...rather it is has the fastest speed discovered till now.It travels in the same wave as light travels i.e tranverse waves.
Is density and speed of light an inverse relationship?
I believe it is. Nobody else does though. Light travels as a wave, just as sound travels as a wave. The speed of light should be inverse to the compression density (and other conditions) of the medium through which it travels. Otherwise we MUST stop describing it as a wave. The very definition of a wave presumes a medium through which it propagates. Light is an omni-directional wave, much like a shockwave, and like a shockwave, it will can be affected in one direction, but unhindered in another by conditions of the medium. Not to render this answer unusable, but I believe that electromagnetic waves are produced by sub-atomic particles breaking the light barrier when super-energized to great speed.
What kind of Wave is an electromagnetic wave how fast does it travel?
An electromagnetic wave is a wave with electric component and magnetic component. In free space (vacuum), an electromagnetic wave travels with the speed of light, that is 3x10^8 m/s. In fact, light is also an electromagnetic wave.
When light travels from air to glass the wave speed decreases B'coz glass is denser than air.?
Correct.
How does a window reflect light?
A window reflects light because light, which is a wave, travels slower in glass than in air. It travels at about 2/3 the speed in glass as it does in air. Also light travels at about 3/4 the speed in water as it does in air and so that is the reason light reflects off the surface of water. The greater the difference in speed between the two mediums, the more light is reflected at the surface boundary. An amazing experiment is to submerge glass in a transparent liquid that has the same "index of refraction". The 'index of refraction" of a substance is simply the measure of the speed with which light travels in the substance. If you submerge the glass, and the speed of light is the same in the liquid as in the glass, the glass seems to disappear. The reason is seems to disappear is because light is no longer reflected off the surface of the glass, and if you think about it, that is the only reason that you can see a glass in the first place.
What equations tell us how fast a wave travels?
Speed of light/wavelength = wave frequency
Energy that travels at speed of light?
That can be light, or some other electromagnetic wave (light is an electromagnetic wave), or gravitational waves.
What is the speed of a light wave that travels at 900000000m in 3 seconds?
900
The denser the medium through which it is traveling the slower a what wave propagates?
Electromagnetic wave, namely, light as it travels through denser medium its speed decreases from its speed when it travels through air or vacuum.
The speed of a wave is how far the wave travels in one unit of?
The speed of a wave is how far the wave travels in one unit of time.
Is it correct to say that in every case any radio wave travels faster than any sound wave?
Yes. Radio is a form of electromagnetic wave, so it travels at the speed of light. Since sound requires a physical medium and it is (theoretically) impossible for matter to attain the speed of light, the speed of sound can never be equal to/above the speed of light, and this statement is correct.
Does color of a laser affects the velocity of the light wave projected by a laser?
No. Light travels at the same speed no matter what.
The speed at which a wave travels through a medium is called?
The Speed At Which Wave Travels Is Known As Wave Velocity.It Is Denoted As 'v' which Equals The Product Of Its Frequency And Wavelength.
What is the speed at which the wave travels?
The speed of waves varies greatly, depending on the type of wave. The fastest waves travel at the speed of light, which is ca. 300 million meters/second.
What is the speed which a wave travels?
The speed of waves varies greatly, depending on the type of wave. The fastest waves travel at the speed of light, which is ca. 300 million meters/second.
