Radiación

The transcript discusses the concept of radiation, specifically ionizing radiation, and its applicability to any form of energy that emanates from a source. It explains that all matter emits small amounts of electromagnetic radiation due to its thermal energy, typically in the form of infrared radiation or microwaves. Additionally, it notes that very hot objects can emit visible light.

What is ionizing radiation primarily associated with?

• A type of sound wave

• A form of energy from a source

• A chemical reaction

• A type of magnetic field

What causes all matter to emit small amounts of electromagnetic radiation?

• Its chemical composition

• X-rays

What is a common characteristic of very hot objects in terms of radiation?

• They become invisible

• They reflect all radiation

• They emit visible light

• They absorb all light

Which of the following is NOT a form of electromagnetic radiation emitted by matter?
