No, flashlights do not use electromagnetic waves to create light. Instead, they use electrical energy to power a light source, such as a bulb or LED, which emits visible light when energized. Electromagnetic waves are a form of energy that can transmit light, but they are not the source of light production in a flashlight.
Holograms use coherent light waves, typically laser light, to create interference patterns that produce a 3D image. These waves are usually produced by a laser that emits a single color and have consistent phase relationships with each other to create the detailed images seen in holograms.
Cellphones use radio waves for transmission and reception of signals. These waves are a type of electromagnetic radiation that falls within the radio frequency range.
Cellular telephones use radio waves to transmit and receive signals. These radio waves are a type of electromagnetic wave that allows for wireless communication between devices.
Some jobs that deal with light waves include optometrists who study how light interacts with the eye, optical engineers who design and develop optical systems, and astronomers who use light waves to study celestial objects in space. Electrical engineers and physicists also work with light waves in areas such as telecommunications, fiber optics, and photonics.
A light microscope uses visible light waves to illuminate and magnify specimens. These microscopes magnify objects by passing light through a series of lenses to focus on the specimen, allowing for detailed observation at the cellular and molecular level.
It doesn't 'USE' any; that is, you don't have to provide any electromagnetic waves in order for a light bulb to do its job.In the course of doing its job, the light bulb PRODUCES light and heat waves.A fluorescent light also produces radio waves.
They most use infa red but they use wireless for the more recent technology.

They use their eyes
Most of these networks use radio waves for their transmission medium, but some use infrared light waves

Radio waves, sounds waves arn't electromagnetic waves.
To see things.
They dont need it, but they can use it
