What is the difference between X-ray light and gamma ray light?

Back

X-ray light has lower energy than gamma ray light and is primarily used in medical imaging, while gamma ray light has higher energy and is often associated with radioactive materials.

What is ultraviolet (UV) light?

Back

Ultraviolet light is a type of electromagnetic radiation with a wavelength shorter than visible light but longer than X-rays, and it can cause certain materials to fluoresce.

What is fluorescence?

Back

Fluorescence is the process by which a substance absorbs light at one wavelength and then re-emits it at a longer wavelength, often visible light.

How does light energy affect materials?

Back

Light energy can be absorbed by materials, causing changes such as heating, fluorescence, or chemical reactions depending on the type of light and the material.

What is the role of energy in light interactions with materials?

Back

Energy from light can be absorbed by materials, leading to various effects such as heating, color change, or luminescence.

What happens when light is absorbed by a material?

Back

When light is absorbed by a material, it can increase the energy of the material's atoms or molecules, leading to changes in temperature or state.

What is the significance of the wavelength of light?

Back

The wavelength of light determines its energy and type; shorter wavelengths (like UV and X-rays) have higher energy, while longer wavelengths (like IR) have lower energy.

What is the difference between visible light and other types of electromagnetic radiation?

Back

Visible light is the portion of the electromagnetic spectrum that can be seen by the human eye, while other types, like UV and IR, are not visible.
