Frequency - Very low usually from about 30 Hz to 300 GHz.

Key Fact - They’re used mainly for communication because they can travel long distances and move through walls buildings and other objects.

Talking on cell phones - Your phone sends your voice using radio waves so someone else can hear you.

Frequency - About 300 MHz to 300 GHz

Key Facts - Microwaves can pass through clouds, smoke, and light rain, which is why they’re used for cooking in microwave ovens and sending Wi-Fi signals for internet connections

Frequency - between 300 GHz and 430 THz

Key Facts - infrared waves carry heat, which you can feel when standing in sunlight

Thermal Cameras -They use infrared to detect heat. Helps people to see in the dark

Frequency: From about 430 THz to 770 THz .

Key Fact - Different wavelengths of visible light are seen as different color - red has the longest wavelength, violet has the shortest.

Photography - Cameras capture visible light to create pictures.

Frequency - from 800 terahertz to 30 petahertz

Key fact - some insects, like bumblebees, can see them, using them to find pollen on flowers, while humans cannot see UV light.

Water purification - people use UV light to kill all the germs in the water so that the water becomes safe to drink

Frequency - is roughly 30 petahertz to 30 exahertz. 

Key Fact - They were called "X-rays" because their nature was unknown at the time, and "X" is often used to denote the unknown.

Airports - X-rays are used in airport and other security systems to detect contraband items like weapons and explosives. 

Frequency - 30 exahertz

Key fact - Gamma rays are so powerful that they can pass through most materials

Engine- Engineers use gamma rays to check materials like metal for hidden cracks, ensuring buildings, planes, and other structures are safe and reliable.
