Black is not light. Black is the lack of light.
When light is traveling away from a black hole, its wavelength becomes longer. This is called blue-shifting. If it's going in, the wavelength becomes shorter, which is called red-shifting.
If the frequency remains constant, then the wavelength increases.
Nothing happens better you get escape from there
The wavelength is halved.
you cant see
As wavelength increases the frequency decreases.

The wavelength gets shorter.
Frequency = Speed of Light / Wavelength.As you can see from this formula, when the wavelength increases the frequency decreases.For example, we will say that the standard wavelength is 5m.F = 3.0 x 108 / 5= 60,000,000 hertzSay if we increased the wavelength to 6m:F = 3.0 x 108 / 6= 50,000,000 hertzAs you can see, if we increase the wavelength, the frequency decreases.If we decreased the wavelength to 4m:F = 3.0 x 108 / 4= 75,000,000 hertzAs you can see, if we decrease the wavelength, the frequency decreases.
The wavelength stays constant.
Wavelength is halved.
Wavelength = 1/frequency. If you double the frequency, the wavelength drops to half.
