These waves are used as energy in everyday life. For example, X-rays and gamma rays are used in medicine to treat internal organs. Radio waves have lower frequencies and longer wavelengths than microwaves. They are used to transmit television and radio programs. This also leads the waves to be related to technology because  when radio waves are used to transmit programs or when x-rays are used they are both technology.]]> 2017-03-02 01:08:00 UTC https://padlet.com/arey0402/cdweuwddhfp6/wish/157210116 arey0402 https://padlet.com/arey0402/cdweuwddhfp6/wish/157213241 All the different kinds of electromagnetic radiation are essentially to life on earth just like light: they're forms of energy that travel in straight lines, at the speed of light (300,000 km or 186,000 miles per second).]]> 2017-03-02 01:35:50 UTC https://padlet.com/arey0402/cdweuwddhfp6/wish/157213241 arey0402 https://padlet.com/arey0402/cdweuwddhfp6/wish/157213387 *Radio waves: Radio waves cover a huge band of frequencies, and their wavelengths vary from tens of centimeters for high-frequency waves to hundreds of meters for lower-frequency ones.
*Microwaves: Is used for transmitting information in radar equipment. Microwaves are like short-wavelength radio waves.
*Infrared: A kind of invisible "hot light". Although we can't see it, we can feel it warming our skin when it hits our face—it's what we think of as radiated heat.
*Ultra-violent: A kind of blue-ish light just beyond the highest-frequency violet light our eyes can detect. The Sun transmits powerful ultraviolet radiation that we can't see.
*X-rays: A very useful type of high-energy wave widely used in medicine and security.
*Gamma rays: These are the most energetic and dangerous form of electromagnetic waves. Gamma rays are a type of harmful radiation.
