    Suppose we have two wave generators within the lab
    and they are producing two "objects" (sine waves)
    interfering with each other so they cannot be detected.

    Its contradictive to describe the situation in ordinary language:

    Two non existing objects exists simultaneously in the lab with no way of detecting that?

    Aint this experiment weird? What is wrong?

    why they can not be detected ? sound waves, light waves etc are Sine waves Why non existing objects ?

    I discuss the situation where the waves interfere with each other...We can look at a pond of water . If you drop a coin you will see expanding waves...i dont know the proper name in english... circles. originating from where the coin was dropped. If you drop two coins at the same time with a distance between the coins you will get expandig circles and att some places where they meet the circles will interfere with each other and destroy each other and calm spots of water will appear. I suppose the waves come back after the meeting points are passed so only att the mmeting points the waves dont exist...but how can they reappear...do they actually?

    The disappearence is explained by claiming that a maximum meets a minimum resulting in the normality as if no waves were there. Is it clear now what im thinking of? No mystery huh? I have heard that more surprising results can be had in the lab...looking att disappearing parts of waves on water is not very impressive I suppose.

    I suppose the two waves I try to describe wont disappear totally in the lab...Have you seen the experiment?
    I dont dream it up you know. Its a real demonstrable effect... But...If you are as bewildered as I am then I guess we have to wait for expertise to arrive!
