Speed of red light and blue light in a vacuum?
In 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.
What is e mc mean?
* E = total energy, * m = mass, * c = the speed of light in a vacuum
How does the average speed of light in glass compass with its speed 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 .
What is the ratio of the speed of light in a vacuum to the speed of light in a different medium?
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.
Why is the speed of light limited in a vacuum?
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.
How light energy different from other energy?
It can travel through a vacuum.
Structure and functions of the equipment used to produce wave energy?
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.
Which gas is used in electric bulbs?
Different kinds of light bulbs used different gasses. The incandescent bulb uses no gas - it uses a vacuum. Other kinds of bulbs may use nitrogen, argon, neon, or krypton.
A light bulb changes electrical energy to what other kinds of energy?
Heat and light
What 3 kinds of energy are involved when a light bulb is turned on?
kinetic,potential,light energy
What is the four kinds of energy?
Four kinds of energy are:1. Mechanical energy2. Chemical energy3. heat energy4. Light energy
How are light and sound different?
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".
What is the relationship between light and the speed of light?
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.
What is the different between light energy and 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.
What travels through a vacuum?
Energy. Light and radio waves etc.
Can all forms of energy travel in a vacuum?
No, all forms of energy cannot travel in a vacuum. We know that electromagnetic energy (like light or radio waves) can travel in a vacuum. So can gravity waves. But mechanical energy (like sound) cannot.
What two kinds of energy are produced from radiant solar energy?
Light and Sun
