Electromagnetic Spectrum Wavelengths For Kids Radio waves have the longest wavelengths of all the electromagnetic waves. they range from around a foot long to several miles long. radio waves are often used to transmit data and have been used for all sorts of applications including radio, satellites, radar, and computer networks. microwaves. microwaves are shorter than radio waves with. Electromagnetic waves are like invisible magic waves that can travel through the emptiness of outer space. they are created when electric charges wiggle back and forth. this wiggling makes electric and magnetic fields that move together in waves. what’s super special about electromagnetic waves is that they don’t need anything to travel.
Electromagnetic Waves Examples For Kids 4. build a simple motor. in the build a simple electric motor! project, students make a simple motor that is similar to the homopolar motor described above but uses a permanent magnet and electromagnet in a different configuration. once the motor is created, the wire coil will spin about the axle of the motor. Students learn the basics of the electromagnetic spectrum and how various types of electromagnetic waves are related in terms of wavelength and energy. in addition, they are introduced to the various types of waves that make up the electromagnetic spectrum including, radio waves, ultraviolet waves, visible light and infrared waves. these topics help inform students before they turn to. Examples of waves include sound waves, water waves, and electromagnetic waves. all waves can be described by their amplitude, frequency, and wavelength. amplitude is the height of a wave from its resting point. waves with larger amplitude transfer more energy. for example, louder sound waves have a larger amplitude than quieter sound waves. There are lots of examples of electromagnetic waves close electromagnetic waves a group of transverse waves which travel at the speed of light, including radio waves, microwaves and visible light.
