Light changes speed when it passes through a transparent substance, based on the refractive index. For diamond, the dense crystal slows light to less than half of its velocity as measured in a vacuum.

What type of speed is light?

Light is a type of wave; it is not a type of speed.


Does speed of light depend on wave or particle nature?

No.


Why was measuring the speed of light so important in deciding whether light was a wave or particle?

The speed of light was predicted, by the English physicist and mathematician James Maxwell, before it was measured. His work showed that electric and magnetic fields could combine to form electromagnetic waves, and his wave equation showed what their speed would be. Other physicists soon succeeded in creating electromagnetic waves in the laboratory, and detecting them all the way across the room. It was suggested that light might also be an electromagnetic wave. One way to settle the question would be to measure its speed, and see whether it was anywhere near the speed predicted by Maxwell's electromagnetic wave equations. All of that has nothing to do with the wave/particle duality of light. There's no decision to make, because light is both. If you design an experiment to look for wave behavior, light has it. And if you design an experiment to look for particle behavior, light has that too.


How can the nature of the source of light wave can influence the speed of light in a vacuum?

The speed of light in a vacuum is constant at about 3 x 10^8 meters per second. The nature of the source of the light wave does not directly influence the speed of light in a vacuum. The speed of light is determined by physical constants in the vacuum, such as the permeability and permittivity of free space.

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.


Which statements are incorrect about wave-speed?

"Wave speed is determined by the frequency of the wave." - Incorrect. Wave speed is determined by the medium through which the wave is traveling, not the frequency. "The amplitude of a wave affects its speed." - Incorrect. The amplitude of a wave does not affect its speed, but rather it affects the intensity or energy of the wave. "All waves travel at the same speed in a vacuum." - Incorrect. The speed of light waves in a vacuum is constant, but other types of waves (like sound waves) can have different speeds depending on the medium.


What wave property affects the speed of a wave?

Both the wavelength and the frequency of a wave affect the speed of a wave.


Is the wave speed dependent on the amplitude?

No, the wave speed is not dependent on the amplitude of the wave. The speed of a wave is determined by properties of the medium through which it travels, such as its density and elasticity. Amplitude only affects the intensity or strength of the wave, not its speed.


What factor that affects the speed of a wave?

One factor that affects the speed of a wave is the medium through which the wave is traveling. Waves travel faster in denser mediums, such as solids, compared to less dense mediums like gases. Additionally, the temperature of the medium can also influence wave speed.


How does the speed of a photon compare with the speed of an electromagnetic wave?

Light can be considered as a wave, or as a particle. As a particle, the particles are called photons. As a wave, light is an electromagnetic wave. In either case, the speed of light (in a vacuum) is approximately 300,000 km/sec.


Why does light have a speed?

Light is an electromagnetic wave and, like all waves, it has a speed.


What is the speed of a light wave that travels at 900000000m in 3 seconds?

The speed of the light wave is 300,000,000 meters per second.


What is the relationship between the wave phase and the propagation of light in different mediums?

The relationship between the wave phase and the propagation of light in different mediums is that the phase of a light wave changes as it moves from one medium to another. This change in phase is due to the difference in the speed of light in each medium, which causes the wavelength of the light wave to either stretch or compress. This phenomenon is known as refraction, and it affects how light travels and interacts with different materials.

Do the color of a laser affects the velocity of light wave by the laser?

No. The color is determined by the light's *frequency*, but, as Einstein proved, there is one and only one velocity at which light can propagate, c or the speed of light. All light propagates at this same velocity (there are ways to slow it down slightly, e.g. by passing through dense material, but this affects all light the same). The speed of light being a constant is one of the very foundations of modern physics.
