How does light wavelength affect color?

What is the relationship between light wavelength and color?

Light wavelength determines the color we perceive. Shorter wavelengths correspond to blue and violet, while longer wavelengths appear red.

Can you explain why the sky is blue?

The sky appears blue because shorter wavelengths of light scatter more in the atmosphere, making blue light more visible.

What happens to color perception in low light?

In low light, our eyes rely more on rod cells, which are sensitive to light but not color, leading to a loss of color perception.

Are there colors that we can't see?

Yes, there are wavelengths outside the visible spectrum, like ultraviolet and infrared, which humans cannot see.
