yes the light will be made up off different wavelenth ray's depending on what star ur talkin bout, a torch works beacuse you exite the atoms in the filament, and a star is burning fuel, the color or the torch is probible a coating on the filament, and the color in a star is determand by the elements being used as fuel at the time! but essentaly the light is the same, it isent really anything its just energy

Both the light from your torch and the light from the star consist of photons. Each photon has an energy and a direction, the the distributions of energies and directions from the two sources are different. One big difference is that there are many more photons coming from the star, although the star is really far away and so the number of photons from the star hitting your eye may be much less than the number of photons from the torch that hit your eye. This makes the star look dimmer than your torch. The distribution of energy of the photons from your torch and the distribution of energy of photons from some reddish-yellow stars is appproximately "a black body at 3000 degrees Kelvin", because in both cases the photons come from a surface that is about that hot.

Torch simply means A portable means of illumination such as a piece of wood or cloth soaked in tallow or an oil lamp on a pole, sometimes carried ceremonially. However, Torch Light is a UK term and Flash Light is USA term for the same device. To throw some more light on what i am talking about check these words biscuits and cookies, platform and side walk...

Yup, The sun transmits the entire spectrum, your torch?, only transmits a limited range of frequences.
Look at the light reflected off the face of a CD disk, in the sun and then at night with your torch, see the difference in the range of colours reflected, interesting eh?

Most definately, whats the biggest battery a torch uses?
How bright are stars? enough said. Some of them torches are bright though!!!!

It is possible to break down light into component frequencies - this produces a unique "barcode" which can tell us, for example, which elements are present in stars. Your torch will have different elements producing the light, and so it will have its own colour and components.

Only that a star don't run out of batteries quite so soon.

One is artificial and costs money, the other one is natural and free.
Maybe the color, maybe the intensity is different.
Basically there is no difference. Both are electromagnetic waves, also described as a shower of photons.

You seem obsessed with your torch - is it an extension of your manhood?

You have new batteries for a star? I congratulate you!
