    Why is it light with white curtains?

    At school i was taught that white reflected all the coloured light. It was the "all" colour.

    Black on the other hand didnt reflect nuttin'. Nuttin' at all.

    So why does all the sunlight come through white curtains while black curtains leave the room nice and dark???????

    If i could be arsed i'd open a new browser tab and go to google. but i cant so enlighten me (bahahahahaha)

    Yes I picked the wrong day to give up sniffing glue.......

    because its a fabric not a solid, and lets the light pass through the gaps in the fabric... Anything solid will reflect including black, (you still get a glare off a matt black object showing it is reflecting light, its just some reflect more than others.

    But the curtains are made out of the same fabric. the black ones let less light through.

    Are you sure? Or is it just that the light getting through is a different color?

    More worryingly, is light a particle or a wave?

    That would be most likely or somewhere along thoughs lines

    The black curtains are "wavey". ergo they must be at the right wavelength to cancel out the light wave! particle schmarticle.

    With the development of quantum mechanics in the 20th century came the decision that it's both! Light can act like a particle and a wave and the same time. We just see different aspects of its nature at different times. If this at all seems strange, don't worry. Quantum physics is confusing to most people, even to the people who invented it!

    That would explain why some light gets through the wavey black curtains!

    where did that cat come from?

    Coz the black absorbed more light on the way through

    Light rides on a particle wave called taceons which makes it visible light and visible light waves are the only electromagnetic waves we can see. We see these waves as the colors of the rainbow. Each color has a different wavelength. Red has the longest wavelength and violet has the shortest wavelength. When all the waves are seen together, they make white light.


    Light is a form of energy visible to the human eye that is radiated by moving charged particles. There are many unanswered questions about light. Light is very hard to study due to its high speed. One major question about light is the uncertainty of whether light is a wave or whether it is a particle. The is some evidence pointing in both directions but no conclusive proof confirms that it can be classified as either one. Scientists have learned through experimentation that light behaves like a particle at times, and like a wave at other times. Whenever light acts like a particle, we called the particles that make up the light either a photon or quantum. In 1900, Max Planck proposed the existence of a light quantum, a finite packet of energy which is a photon.

    F-ing tell me about it, probably the only course I never missed a lecture of, had perfect notes for and yet still gives me total brain-ache....atomic physics was a piece of cake in comparison

    But getting back to Usaka's original question - you also need to consider the effects of absorbtion
