∙ 10y agoIn a vacuum the speed of red and blue light are the same as all light, 300,000,000m/s. Their frequency and wavelength will be different but the speed remains the same.
* E = total energy, * m = mass, * c = the speed of light in a vacuum
There are several different types of glass, and light has a somewhat different speed in each of them. On the average, the speed of light across all typical types of glass is in the neighborhood of 2/3 its speed in vacuum, or around 200,000 km/sec .
This is called the index of refraction. When light crosses the boundary between mediums (media) with different indices, it is bent (refracted).It's usually defined the other way around ... the ratio of the speed of light in vacuum to its speed in the medium. Since the speed of light is greater in vacuum than in any medium, the number is always greater than 1. It's referred to as the "refractive index" of the medium.
The speed of light is not limited in a vacuum - the speed of light is fastest in a vacuum. But that is what Einstein called the "Cosmic Speed Limit" - nothing can move faster than the speed of light in a vacuum, or even quite asfast.
It can travel through a vacuum.
There are many different kinds of waves, and many different kinds of wave energy, and many different kinds of equipment used to produce such energy. For example, a lightbulb, since light is a form of electromagnetic wave.
Heat and light
Different is the speed of propagation. Scroll down to related links and look at "Acoustic or sound waves in air - Radio and light waves in a vacuum".
Four kinds of energy are:1. Mechanical energy2. Chemical energy3. heat energy4. Light energy
Sound energy and light energy are both forms of energy that travel in waves. They can both be transmitted through a vacuum and can be reflected, refracted, and absorbed by different materials. Additionally, both sound energy and light energy are forms of kinetic energy that can be used to perform work.
The LED (light-emitting diode) is similar to the light bulb as it also produces light, but it is more energy-efficient and longer-lasting.
Yes, there are different kinds of light including visible light, ultraviolet light, and infrared light. Each type of light has its own unique properties and wavelengths.
Energy is directly proportional to the square of the speed of light (in vacuum), where the constant of proportionality is the mass equivalent of the energy.
Lots of differences. For example: light is a flow of electrically neutral particles (called photons), that move at the speed of light (at least, in a vacuum). Electricity is a flow of charged particles - often electrons - that move at speeds below the speed of light.
Light and Sun
Sound and light are both forms of energy that is carried from one place to another.they travel in all directions from the source.
