EM WAVES
Storyboard-Text
- Microwaves are most commonly used insatellite communications,radarsignals, phones, and navigational applications. Other applications where microwaves used are medical treatments, drying materials, and in households for the preparation of food.
- Usage of Infrared Waves
- Thermal-imaging cameras are used to detect heat loss in insulated systems.Infrared radiationis used in industrial, scientific, military, commercial, and medicalapplications.
- Potential applications of VLC include Li-Fi, vehicle to vehiclecommunication, robots in hospitals, underwatercommunicationand information displayed on sign boards. The Li-Fi uses visible light forcommunicationto provide high speed internet up to 10Gbits/s.
- UV radiation is widely used in industrial processes and in medical and dental practices for a variety of purposes, such as killing bacteria, creating fluorescent effects, curing inks and resins, phototherapy and sun tanning. Different UV wavelengths and intensities are used for different purposes.
- X-raysplay an important role in the fight against cancer, with high energyradiationused to kill cancer cells and shrink tumours. Patients undergo treatment outside the body (known as external-beamradiation therapy) or from radioactive material that's inserted into the body in close proximity to cancer cells.
- X- rays are electromagnetic waves that have the higher frequencies than ultraviolet rays.
- It's called Lead Aprons it's use to protect himself from unnecessary radiation during the procedure
- Gamma raysare ionizing electromagneticradiation, obtained by the decay of an atomic nucleus.Gamma raysare more penetrating, in matter, and can damage living cells to a great extent.Gamma raysare used in medicine (radiotherapy), industry (sterilization and disinfection) and the nuclear industry.
- Sir, my grandpa had a check up a month ago, I'm just wondering why did they put something like covering during his x-ray
