Infrared waves are a part of a big family called the electromagnetic spectrum. They are found in many home appliances and can be very helpful. The wavelengths of these waves range from 700 nanometers to 1 millimeter, which makes them great for different types of technology.

Here are some everyday uses of infrared waves:

1. Remote Controls

   • Most remote controls, like those for TVs and DVD players, use infrared signals. They usually send out light that is about 950 nanometers long. In fact, studies show that around 90% of homes in the UK have at least one remote control.

2. Infrared Heaters

   • Infrared heaters work by using infrared waves to directly heat people and objects, instead of just warming the air. They are very effective, converting about 90% of energy into heat, which helps lower heating bills. More and more homes are choosing these heaters, with an increase of about 30% every year.

3. Thermal Cameras

   • Infrared technology is also used in thermal cameras, which help with home security. These cameras can see heat from people and warm objects. They are so precise that they can notice temperature differences as small as 0.1°C, making homes safer.

4. Food Preparation

   • Microwave ovens use infrared waves to keep food warm and cook it evenly. They are pretty energy-efficient, using about 50-65% of the energy they consume for cooking. This means they can cook food faster than regular ovens.

These examples show how infrared waves are important for making our daily tasks easier and more efficient.
