Light is a magical form of matter, the photon is composed of photons have both particle and volatility, the wave is a change in the electromagnetic field, we have the universe of non-conductive neutral substances defined as the optical matter.
The wavelength of light refers to the distance between the two peaks (or troughs) of an optical wave in the horizontal direction, and the frequency of the light can be understood as the number of peaks (or troughs) of light passing through at a point in the unit time.
The color of visible light is determined by the wavelength, and the type of non-visible light is the wavelength from short to long: Gamma, X-ray, ultraviolet, visible, infrared, microwave, radio waves.
In Planck's quantum principle, light (or other classical waves) can only absorb discrete quanta, whose energy is proportional to the frequency, inversely proportional to the wavelength, i.e. the higher the frequency, the shorter the wavelength, and the higher the energy.
According to Einstein's energy equation: e=mc², the greater the velocity of the object, the greater the energy needed to accelerate, and the infinitely large energy needed to accelerate when the object is infinitely near the speed of light, which in theory is not permissible, so that no object can be faster than the speed of light.
We know that the light emitted by galaxies far away from us takes a certain amount of time to reach us, which affects us. Similarly, any event in the universe takes some time to influence other events, since the speed of light is the largest velocity in the universe (excluding wormholes), so the fastest speed at which other events are affected is the speed of light.
If we extend the speed of light outward at an event, the cone-like thing called the light cone, called the future light cone extending to the future (i.e., after the current time), represents the set of events that the event can affect, and extends to the past (that is, the current time), known as the past light cone, which represents the set of events If the gravitational effect is not taken into account, the light cone is generally absolute upright, otherwise the light cone can point in any direction.
Suppose an object passes through the worm hole above the speed of light, it looks like it is crossing over to the past, as it will see the light emitted from its departure at its destination, as if it had not yet started, and it would first see the light from the previous second and see the light emitted by the first two seconds ... It looks like it's time to go backwards.
Light also has a Doppler effect, if the light source is far away from us (relatively) then the wavelength of light will become longer, that is, to the infrared, radio waves moving, we call the light of the red shift phenomenon, the opposite will be moved to ultraviolet rays, gamma rays, we call the light of the purple shift (as if it is called purple).
For two beams of the same wavelength, if the position is exactly the crest corresponding to the trough, the two beams will cancel each other out (I've been thinking, what about their energy?). If peaks correspond to peaks, troughs correspond to troughs, their frequencies (i.e. brightness) are added together to synthesize a beam of light.
What if a light source (large enough), such as a specific color (that is, a particular wavelength) bulb, is illuminated on a screen by a partition with two flat presidents sewn on it? Most people will think that there will be two of light seam on the screen, some people will think of small hole imaging, but in fact there will be a lot of parallel light seam (that is, dark stripes), because after the keyhole imaging, some areas of the light will be offset, and some places will be strengthened, so there is a dark stripe.
There is also the theory that heavy loads can stall time, and there is a certain light effect. The heavier the object, the greater the gravitational field, which causes the light to lose energy, and then its frequency decreases, and in the distance it seems to be the time of the event to grow, and in the 1962, people used two very precise clocks mounted on top and bottom of a water tower to verify the claim that The bell of the tower closer to Earth is slower than the bell on the tower.
