Camera autofocus systems typically use infrared (IR) electromagnetic waves. These IR waves are emitted by the camera and reflected off subjects to determine distance and focus. Some advanced systems may also utilize visible light or laser technology for faster and more precise focusing. Overall, the key role of these electromagnetic waves is to assess the distance to the subject for optimal focus.

How are em waves used in dentistry?
EM waves stands for Electromagnetic Waves. The EM waves used in dentistry are usually X-Rays. These electromagnetic waves go through your skin and other body tissue (don't worry it's not very harmful or bad for you). And reflect off your bones. Think of it as a camera, the X-Ray machine sends out a flash, then takes the picture. This 'picture' shows where your bones are and whats happening to them, like, are they coming out as an adult tooth? or will you need braces in a few years. That sort of thing.
Are em waves longitudinal are transverse?
EM waves are both Transverse and Longitudinal.
Type of radio waves that excites water molecules?
Radio waves are a form of electromagnetic radiation. The EM waves used in microwaves are chosen speciiffically for there ability to excite water molecules.
What type of EM waves do we see in the rainbow?
We see visible light waves in the rainbow, which are a portion of the electromagnetic spectrum. These waves are perceived by our eyes as various colors due to their different wavelengths.
