What are examples of non-visible light?
Examples of non-visible light include:
1. Ultraviolet (UV) light: This light has a slightly higher energy level than visible light and is commonly emitted by the Sun. It is responsible for causing sunburns and is used in various applications such as sterilization, fluorescent lighting, and counterfeit money detection.
2. Infrared (IR) light: This light has a slightly lower energy level than visible light and is commonly emitted by heat sources. It is used in thermal imaging cameras, remote control systems, and infrared heating.
3. X-rays: X-rays have high energy levels and are used in medical imaging (X-ray radiography), security scanning systems, and material analysis. They are typically used to visualize bones and internal body structures.
4. Gamma rays: Gamma rays have the highest energy levels among the electromagnetic spectrum and are produced through nuclear processes or high-energy particle interactions. They are used in cancer treatment (radiation therapy), research in nuclear physics, and industrial applications such as sterilization.
5. Microwaves: Microwaves have longer wavelengths compared to visible light and are commonly used for cooking (microwaves), communication (mobile phones, Wi-Fi), and radar systems used in weather forecasting, aviation, and military applications.
6. Radio waves: Radio waves have the longest wavelengths among the electromagnetic spectrum. They are used in broadcasting (AM/FM radio, television), communication (cell phones, Wi-Fi, Bluetooth), and various scientific applications such as radio astronomy.
Examples of non-visible light include:
1. Ultraviolet (UV) light: This type of light has a shorter wavelength than visible light and is emitted by the sun. UV light is responsible for causing sunburns and can be detected using specialized equipment like UV lamps or black lights.
2. Infrared (IR) light: IR light has a longer wavelength than visible light and is emitted by objects that generate heat, such as fire or a warm body. It is commonly used in remote controls, night-vision cameras, and heat-detecting devices.
3. X-rays: X-rays have a much higher frequency and energy than visible light, and they can pass through soft tissues in the body but are blocked by denser materials like bones. X-rays are used in medical imaging to visualize bones and diagnose fractures or other abnormalities.
4. Gamma rays: Gamma rays have the shortest wavelength and highest frequency among all forms of electromagnetic radiation. They are produced during nuclear reactions or by extremely energetic events in space, such as supernovae or black holes. Gamma rays are also used in cancer treatment and some imaging techniques.
