Wave Optics

• Index refraction of water= 1.333
• the range of optical wavelengths contain three bands
• The range of optical wavelengths contains three bands = Ultraviolet, visible and infrared
• Ultraviolet from 10 to 390 nm
• Visible from 390 to 760 nm
• Infrared 760 nm to 1 mm
• Range of optical frequencies stretches 3x10^11 Hz to 3x10^16 Hz
• Optical intensity is defined as the optical power per unit area (W/cm^2) is proportional to the average of the squared wavefunction
• The optical power (units of watts) flowing into an area A. is the integrated Intensity in an Area
