What Is Blue Light?
Sunlight is a vibrant tapestry of colored light rays—red, orange, yellow, green, blue—and countless shades in between, each varying in energy and wavelength. When these rays unite, they form the brilliant 'white light' known as sunlight, which illuminates our world.
In the fascinating world of light physics, it's key to understand: long-wavelength light rays harbor less energy, while short-wavelength rays are bursting with it. This inverse relationship is pivotal in determining the energy power of light.
Rays on the red side of the visible spectrum are characterized by their longer wavelengths and thus, lower energy. Conversely, blue light rays are defined by shorter wavelengths, packing a powerful energetic punch.
Beyond the visible red spectrum lies the realm of infrared rays—these are the invisible, heat-inducing rays. Think of the heating lamps in eateries; they radiate infrared warmth, occasionally accompanied by visible red light as an indicator of their operation, similar to various heat lamps.
At the opposite end, blue light rays boast the shortest wavelengths and highest energy. These potent rays often go by names like blue-violet or violet light. Just beyond them lies the invisible world of ultraviolet (UV) radiation, a powerful presence in the light spectrum.
