The energy of a wave is proportional to its frequency. X rays have a frequency much higher than visible light.

X-rays have higher energy and shorter wavelengths than visible light rays, allowing them to penetrate deeper into materials and tissues. This property makes X-rays useful for imaging bones and other dense structures in the body. Additionally, the production of X-rays involves high-voltage electricity and specialized equipment, contributing to their higher power compared to visible light rays.
To make themselves more visible to polinating insects and absorbe as much visible light as posible.
It is electromagnetic radiation, which is the same in composition as visible light but has a much higher frequency/shorter wavelength, and will do damage to any biological material it passes through. Both travel at the same speed ('velocity of light') but gamma radiation can penetrate material opaque to visible light.
The wavelength of visible light is longer than a human skin cell. Visible light has wavelengths ranging from about 400 to 700 nanometers, while a human skin cell is typically around 30 micrometers in size.
Astronomers study as much of the spectrum of radiation as they can, and the visible spectrum is only a small segment of it.
Exposure to high-intensity visible light, such as from the sun or artificial sources, can potentially cause damage to the eyes, leading to conditions like photokeratitis or photoconjunctivitis. Prolonged exposure to blue light, a component of visible light, especially from screens, may also disrupt sleep patterns and cause digital eye strain. Additionally, visible light can contribute to skin aging and pigmentation.
