Medical Physics

• Medical Physics involves the application of physical principles to medical procedures and technologies
• It encompasses various branches of physics, including Atomic Physics, Nuclear Physics, and Solid Physics

Electromagnetic Waves

• Electromagnetic waves have a wide spectrum, including visible light
• Properties of light include reflection, refraction, interference, diffraction, and polarization
• Visible light is a form of electromagnetic radiation with a wavelength between 400-700 nanometers

Properties of Light and Visual Function

• Light is essential for the visual function, with the human eye capable of detecting a wide range of wavelengths
• The visual system involves the transmission of light from the eye to the brain, enabling us to perceive and interpret visual information

Laser and its Applications in Medicine

• Lasers have numerous medical applications, including surgical procedures, diagnostics, and therapeutic treatments
• Lasers can be used to destroy cancer cells, remove cataracts, and perform cosmetic procedures

Mechanical Waves and Auditory System

• Mechanical waves are responsible for the transmission of sound through the air
• The auditory system involves the detection and interpretation of sound waves, enabling us to hear and process sounds

Ultrasound and its Applications in Medicine

• Ultrasound waves have a frequency above 20,000 Hz and are used in medical imaging and diagnostics
• Ultrasound is used to image internal organs, monitor fetal development, and detect blood clots

High-Frequency Currents and Diathermy

• High-frequency currents are used in medical treatments, including diathermy, which involves the use of heat to treat medical conditions
• Diathermy is used to treat pain, reduce inflammation, and promote healing

Radiation Physics and Nuclear Medicine

• Radiation physics deals with the interaction of radiation with living tissues
