Light consists of many wavelengths.

Explanation:
Light is electromagnetic radiation that travels as waves with different wavelengths, and white light contains many wavelengths across the visible spectrum. Sunlight and most common light sources emit a continuous range of wavelengths rather than just a single one, which is why a prism can split light into a rainbow. Even light that looks like a single color has a small spread of wavelengths due to bandwidth, while truly monochromatic sources (like ideal lasers) are designed to be nearly single-wavelength but still have a tiny range. So, in everyday terms, light consists of many wavelengths, making the statement true.
