No, visible light waves are not longer than X-rays. In fact, X-rays have shorter wavelengths than visible light.
The electromagnetic spectrum consists of various types of waves, each with a different wavelength. Visible light is a part of this spectrum, ranging from approximately 400 to 700 nanometers (nm) in wavelength.
X-rays, on the other hand, have much shorter wavelengths than visible light, typically ranging from 0.01 to 10 nanometers (nm). This means that X-rays have higher energy and are more penetrating than visible light. They are commonly used in medical imaging (such as X-ray radiography and CT scans) and industrial applications.
So, to summarize, X-rays have shorter wavelengths than visible light, making them more energetic and capable of penetrating matter to a greater extent.
