  • Do you know Light Travels in a Straight Line?
    Science Experiment/ Science Project:
    Rectilinear propagation of light.
    In a homogeneous transparent medium, light travels in a straight line and this is known as rectilinear propagation of light. This can be demonstrated by the following experiment.
    Take three cardboard A, B and C and make a pinhole at their centers. Place a burning candle on one side of A and arrange the cardboard in such a way that the three pinholes and the candle flame are in a straight line. The candle flame will be visible through the pinhole of the cardboard C. Now slightly displace any one of the cardboard and try to see the flame through the pinhole of the cardboard C. The flame will not be visible. From this it is clear that light travels in a straight line.
    Thanks for watching our video.

    Light travels in a straight line in class VI; it does not do so in class XII. 😂 It learns how to bend as it grows up.

    I'm not sure what this example proove ?
    If you are in a total pich dark room and use non-reflective cardboard, it is thue that you won't see the light source anymore when you move one of the cardboard, but you will still view light. (Which mean light is not a straight line)

      Yeah his bs is debunked by quantum physics already. There's an experiment that shows multiple dots of one light source proving it's a wave.

      If u r not in any concealed room and in are in a vaccume and repeate this experiment, assuming the cardboard do not allow any photon to pass through then u might not see source .. same might be happening in universe, if a solid planet is in between the path of a star and earth then we might not be able to see that star.

    i think the key work is homogenous medium , can you think of an experiment which would prove light travels in a straight line over lets say 1km in the real world and not a laboratory or magnetically controlled path of some kind . In the real world i think you'll find no such experiment has ever been done ???? i wonder why ?

    I don't think light travels in a straight line light travels in wavelengths and the colour of each light is emitted according to the wavelength

  • @kimbybean001
    @kimbybean001 Před 9 měsíci

    If light travels in a straight line, why can the person filming this also see the light? Even if the candle was a light bulb. Are there 2 straight lines? Also, if there was a person opposite the person filming (if this was not an animation) he too, would see the light. If all people on the dark side of earth were viewing one star at the same time, why can everyone see it at once? If we took a picture of the night sky on January 1st, and viewed all the visible stars and their measurements between other visible stars on the map only, and then repeated it the following year, would all the measurements be the same as the prior year and years to come? Since any 2 stars would literally be light years away from each other and in their own solar system or galaxy, wouldn't their individual orbits be so different that the night sky picture could never repeat itself? Maybe it doesn't already, but I never hear anyone talk about it. Every year at the same time I look up and see the same stars in the same places, even though they are clearly not on OUR solar systems annual clock or orbit. Seems strange to me. How are those star systems in sync with our annual orbit? No, I am not looking at planets.
