Answer 1

Infrared Rays are electromagnetic waves with wavelengths shorter than those of radio waves.

**Higher energy** rays have more energy than **lower energy** waves.

You feel the energy of infrared rays as **heat**.

**Heating lamps** have bulbs that give off mostly infrared rays and very little visible light.

**Infrared heaters** are used to keep food warm or heat up rooms quickly.

Most objects give off some **infrared radiation**.

**Hotter** objects give off infrared rays with more **energy** and higher **temperature**.

Infrared **cameras** take **pictures** using **infrared radiation** instead of **visible light**.

These pictures are called **thermal images**, which is an image that shows regions of different **temperatures** in different **colors**.

Used by **search and rescue teams** to locate people during **emergencies**.
