What is the difference between the light emitted by the moon and the sun?
The sun emits light, which means the electrons in its atoms have so much energy that they rise and fall in the electron cloud giving off light. The moon reflects, light meaning that the source didn’t generate the light; light from another source just bounced off of its surface.
What is the difference between light of sun and light of bulb?
A light bulb converts electricity to photons. Vastly more energy comes from the sun than from any artificial light. But the light from the sun is different from a street lamp another way: most artificial light doesn’t emit as much energy in the red and blue region of the light spectrum as sunlight does.
Does light from a bulb travel at the speed of light?
The short answer is that light coming out of your torch instantly reaches the speed of light. Light can only ever travel at the speed of light — 300,000,000 metres per second in a vacuum, and a bit slower in air because it bumps into molecules.
Does light have different speeds?
Different photons have different energies, which also means their electric and magnetic fields oscillate at different rates. While the speed of all different types of light is the same in a vacuum, those speeds can be different in any sort of medium.
Does the sun reflect light or emit light?
Recognize that the Sun and stars emit the light by which they are seen and that most other bodies in space, including Earth’s Moon, planets and their moons, comets, and asteroids, are seen by reflected light.
Does the moon emit or reflect light?
Unlike a lamp or our sun, the moon doesn’t produce its own light. Moonlight is actually sunlight that shines on the moon and bounces off. The light reflects off old volcanoes, craters, and lava flows on the moon’s surface.
Is light always the same even when it is emitted by different light sources?
We see both the sun and the bulb pretty much emit photons all over the UV/Visible/InfraRed spectrum. But, do so at different intensities. That means there are a different number of photons of different colours impinging into your eye. So the total light, or the spectrum of photons, is not the same.
What type of light does the sun emit?
All of the energy from the Sun that reaches the Earth arrives as solar radiation, part of a large collection of energy called the electromagnetic radiation spectrum. Solar radiation includes visible light, ultraviolet light, infrared, radio waves, X-rays, and gamma rays.
What if I travel at the speed of light?
Firstly, the physical consequence of traveling at the speed of light is that your mass becomes infinite and you slow down. According to relativity, the faster you move, the more mass you have. So, traveling at the speed of light in the conventional way is impossible.
Do all electromagnetic waves travel at the same speed?
Generally speaking, we say that light travels in waves, and all electromagnetic radiation travels at the same speed which is about 3.0 * 108 meters per second through a vacuum.
What is the difference between sunlight and Lightbulb?
There is huge difference in suns light rays and lightbulb. Sun light is very rich in spectrum of various wavelengths of light. Light bulbs are mostly modelled to emit around visible spectrum of light, typically around 1 microm wavelength. Sunlights on the other hand contains spectrum from infrared, visible to ultra violet spectrum.
What does the spectrum of light from the Sun look like?
You are right to say that the spectrum of light from the sun is different that that from a light bulb. The solar spectrum compared to an incandescent bulb (the ones with a filament) looks like this: We see both the sun and the bulb pretty much emit photons all over the UV/Visible/InfraRed spectrum. But, do so at different intensities.
What is the difference between the Sun and the Moon?
The shape of the moon appears to change from night to night whereas the shape of the sun does not appear to change from day after day. This is one of the major differences between the sun and the moon.
Is the Sun hotter than the average light bulb?
Yes! The sun has a photosphere with an effective temperature of around 5800K (degrees Kelvin) while the everyday incandescent bulb has an effective temperature of about half that at 2900K. The result is that the incandescent bulb has far more infrared output than visible and far less ultraviolet.
