spectrum
Radio Waves
UHF :
shorter wavelengths,
do not diffract
VHF :
longer wavelengths,
will diffract
Microwave
Have a shorter wavelength
Higher frequency of all ranges
Visible
Endoscope :
long tube of optical fibers to see abnormalities in organs
Infrared
Wavelengths are longer than visible light
X-rays
X-rays :
pass through flesh to produce images for diagnosing fractures, tooth decay, tumors, and abnormal masses.
CT :
uses low-frequency X-rays and a computer to produce 3D images of soft tissues and bones.
Radiation Therapy :
kills cancerous cells using high-frequency X-rays.
Industrial Radiography :
detects internal defects using high-frequency X-rays and computes images showing cracks or flaws in materials.
UV Rays
Wavelengths :
UV-A (315-399nm), UV-B (280-314nm),
UV-C (100-279nm).
Sunbeds
: UV lamps used for artificial tanning, provide
vitamin D, treat skin conditions.
Fluorescent :
absorbed in UV, materials convert energy
into light and glow.
Sterilization :
UBV & UVC radiations used to sterilize food
and medical equipment.
Gamma Rays
Gama rays :
higher energy than X-rays, highly penetrating and can pass through metals, used to treat cancer, radiograph holes, and defects in metal castings
Knife Radiosurgery :
medical procedure using gamma rays to destroy small tumors in the brain.
PET :
medical imaging method, computer generates image highlighting location of biological process.
