how much energy does it take to travel at the speed of light?
440950
e = approximately 2.246 x 10^18 foot pounds of energy to move an average weight person at 99.99% the speed of light. This is all based on very generalized assumptions. It would require a huge amount of fuel to even get an object of 150 pounds to reach that speed, in any medium, even in a vacuum.

Actually, radio waves travel very quickly through space. Radio waves are a kind of electromagnetic radiation, and thus they move at the speed of light. The speed of light is a little less than 300,000 km per second. At that speed, a beam of light could go around the Earth at the equator more then 7 times in a second.

What is the energy of a photon of light having a wavelength of 4.5 x 10-7 meters? (Planck's constant is 6.626 x 10-34 joule seconds; the speed of light is 2.998 x 108 m/s) 2.9817 x 10-40 joules. 4.4143 x 10-19 joules.

This sounds like a strange question, but think about it. Sunlight travels at the speed of light. Photons emitted from the surface of the Sun need to travel across the vacuum of space to reach our eyes. The short answer is that it takes sunlight an average of 8 minutes and 20 seconds to travel from the Sun to the Earth.

Science: Can photons travel 'faster than light'? LIGHT cannot travel faster than it does in a vacuum. This, at any rate, is what Einstein postulated in 1905. ... The proposed effect, however, is very small indeed: the photons can exceed Einstein's limit by only one part in 1036.

The energy E, frequency f, and wavelength λ of a Photon are related as follows: E=hf=hc/λ, where c is the speed of light and h is Planck's constant. So, given any one, the other two can be easily calculated. (This is assuming the photon is propagating in a vacuum.

Gamma rays travel faster than visible light. All electromagnetic waves travel at the same speed in a vacuum.
268338
The Gamma rays ( γ- Rays) are also part of the vast EM radiation, so they also travels with the speed of Light c (3 x 10^8 m/s). Gamma-rays are the most energetic form of light, due to their high energy they can be used in cancer diagnosis.

All of these, known collectively as the electromagnetic spectrum, are fundamentally similar in that they move at 300,000 km per second, the speed of light. The only difference between them is their wavelength, which is directly related to the amount of energy the waves carry.
869207
Because it is electromagnetic radiation, gamma photons have no mass and no electrical charge, and they travel at the speed of light (3.108 m.s-1), being able to cover hundreds to thousands of meters in air before spending their energy. Gamma-rays have the smargies above 100 keV).

Sunlight travels at the speed of light. Photons emitted from the surface of the Sun need to travel across the vacuum of space to reach our eyes. The short answer is that it takes sunlight an average of 8 minutes and 20 seconds to travel from the Sun to the Earth.

The Sun is at an average distance of about 93,000,000 miles (150 million kilometers) away from Earth. It is so far away that light from the Sun, traveling at a speed of 186,000 miles (300,000 kilometers) per second, takes about 8 minutes to reach us.

As h and c are both constants, photon energy E changes in inverse relation to wavelength λ. Therefore, the photon energy at 1 μm wavelength, the wavelength of near infrared radiation, is approximately 1.2398 eV. This equation is known as the Planck-Einstein relation.

All electromagnetic waves travel at 300,000 km/s in the vacuum of space. ("Speed of light.") Nothing travels faster than the speed of light.
249673
In a vacuum, all electromagnetic waves travel at 3 × 10 8 m s − 1 - the fastest speed possible. When electromagnetic waves travel through matter (for example, light passing through air or glass), they travel a bit slower than this but rarely less than half as fast as in a vacuum.

The more mass, the more energy is required. By the time an object reached the speed of light, Einstein calculated, its mass would be infinite, and so would the amount of energy required to increase its speed. ... Schneider uses an example of hitting a target with a gun that shoots bullets faster than the speed of light.

Light travels so fast that light emitted from the Sun travels 150 million km to Earth in only about eight and a half minutes. However, when light travels in matter, it interacts with the atoms and molecules in the material and slows down. As a result, light travels fastest in empty space, and travels slowest in solids.
