This is exactly the reason why physicists find it difficult to perform interference experiments, because it is very difficult to find two light sources with exactly the same frequencies. Two waves of different frequencies (however small the frequency difference be) can never completely cancel each other, though two waves of the same frequency but different phases can. So your question can be re-framed as : Is there a possibility that if I get an extremely powerful red laser and point it at a peice of white paper, the color of light reflected is blue rather than red?.or anything else other than red!? And whether or not a photon can cause a chemical change depends upon the electronic energy levels in the molecule being exposed, and the frequency of the photon, not the number of photons. Light is seen by the eye because it can cause chemical changes in pigments. Simply increasing the intensity will not change the properties of the light, it will only increase the number of photons hitting the eye per unit time. You'll only know it when your sensory pigments get totally damaged and you simply cannot see any more! A part of the light will get absorbed and will make the molecules in the eye vibrate and will hence heat up the portions of the eye and cause burn damage much the same as an intense beam of laser does in laser surgery. Yet, this doesn't mean that the light is getting reflected completely simply because it cannot excite the electrons in specific chemical pigments properly. This means that the electrons in the sensory pigments at the back of the retina cannot be excited by UV light in a way that can make our brain register the signal as a colour. UV light (as Dr Jh pointed out) is not in the visible spectrum for the human eye. Also, there is a difference between seeing and feeling. In optics, black is the absence of a colour.and these are two different things which is exactly why you can't feel or see vacuum simply because vacuum is the "absence" of matter. What you need to understand is : "Black" is not a color.

You just need to have an attentive eye or a high-sensitivity device to perceive the particle aspect of these lights.Īs a result, the Black Light exists in the Nature and has its special particle state and its particular effect.My simple question to you: Have you ever seen some "black light" coming out of your TV remote, or the microwave oven? In the upper partially visible region there are different spectrums with a various colors including the spectrum of Black Light. Then we can consider the photon as a tiny but effective bullet. The photon therefore can have the same influence as a bullet, that can transmit its energy, imposes itself on the target and changes its form Just about the photon we could take the example of the discoloration of clothes or the dimensional distortion of a plastic object when overexposed to the light. As a particle, it is an obvious entity that has its effect, a concrete effect with its own energy and power. The photon exhibits properties of both wave and particle. We have known that the color of the photon (of the spectrum) is designated by its gyroradius. On the upper region, of frequency, the lights have a particular brightness and are of different colors. If a witness or observer has an attentive eye or possesses a high-sensitivity device, he can see the partially visible area - that contains colored packets of energy too - as clear as the visible region. The lower region called Infrared and the upper one called Ultraviolet. Apart from this, there is also the partially visible region that is clearly perceptible for two observer groups. It contains packets of elemental energy, from red to violet. The domain of electromagnetic spectrum is very large and a small region of it is called the Visible Region. This courageous minuscule has brought us with him the lighting of life, the existence, the heat. The photon, as a messenger, revive the past moments as a little angel illustrates the whole universe without it, the darkness would dominate the universe. If you look at the corners of the Universe, you see flashing lights that come to you and carry the secrets of 13 billion years ago. Know that the photon has a short life but also a long life you’d think that it has seen the whole Universe. Victor Hugo in the last moment Black Light
