Electromagnetic Spectrum
What way is frequency at most energy?
Right
Radiowaves - frequencies and what it's used for
frequencies: range are less than 3x10 to the 9th power
used for: radar, satellite transmissions
Reflection
the turning back of a wave when it reaches the boundary of the medium thru which it's traveling
Which way is the wavelength longest?
Left
Microwaves: frequencies and what it's used for
frequencies: range from 3x10 to the 9th power to 3x10 to the 12th power
used for: microwaves, cell phones
Refraction
the bending of a wave as it passes obliquely from one medium into another of different propagation speed
Which electromagnetic wave has the lowest energy?
Radiowaves
Infrared: frequencies and what it's used for
frequencies: range from 3x10 to the 12th power to 4.3x10 to the 14th power
used for: finding people in dark and in the tv remote control devices.
Diffraction
the spreading of a wave around a barrier or thru an opening
Gamma Rays
Visible light: frequencies and what it's used for
frequencies: range from 4.3x10 to the 14th power to 7.5x10 to the 14th power
used for: light
Resonance
vibration of an object caused by another vibration at the object's natural frequency
Which electromagnetic wave is in the middle for both wavelength and frequency?
Ultraviolent: frequencies and what it's used for
frequencies: range from 7.5x10 to the 14th power to 3x10 to the 17th power
used for: uv light etc
Polarization
action of restricting the vibrations of a transverse wave to one single direction
