The same ones used in the camera for taking the pictures, usually the visible light spectrum waves.
Some older autofocusing systems (e.g. one used on some Polaroid instant cameras) used a SONAR ranging system, which used sound waves not electromagnetic waves.
The type of electromagnetic wave used for TVs is radio waves. Specifically, TV signals are carried on radio frequencies within the electromagnetic spectrum.
Light is an example of a electromagnetic wave.
A gamma ray is a type of electromagnetic wave that has the highest frequency and energy in the electromagnetic spectrum. It is a form of ionizing radiation.
Radio waves are a type of electromagnetic wave. They do not require a medium to travel through and can travel through a vacuum, unlike mechanical waves which require a medium, such as air or water, to propagate.
MRI uses radiofrequency electromagnetic waves to create detailed images of the body's internal structures.
A mechanical wave is not an electromagnetic wave.

A laser generates an electromagnetic wave operating at light frequencies.
Light is an example of a electromagnetic wave.
Ultraviolet Radiation
It is UltraViolet Radiation
Radio wave
Ultraviolet light.
It produces an UltraViolet electromagnetic wave. This can vary because there are several different lasers that can be used in lasik surgery.
