CHEMISTRY- 8.2 The Nature of Light- STUDY GUIDE
WITH 100% CORRECT SOLUTIONS
Wave-Particle Duality - ✔✔Light exhibits both wave and particle characteristics.
Electromagnetic Radiation - ✔✔Energy in oscillating electric and magnetic fields.
Magnetic Field - ✔✔Space where magnetic particles experience force.
Electric Field - ✔✔Space where charged particles experience force.
Amplitude - ✔✔Height of wave crest; determines light intensity.
Wavelength (λ) - ✔✔Distance between adjacent wave crests; measured in meters.
Frequency (ν) - ✔✔Number of wave cycles passing a point per second.
Hertz (Hz) - ✔✔Unit of frequency; 1 cycle per second.
Speed of Light (c) - ✔✔Constant speed of light in a vacuum.
Intensity - ✔✔Brightness of light; related to amplitude.
Color of Light - ✔✔Determined by the wavelength of the light.
Propagation - ✔✔Movement of light waves through space.
, Vacuum - ✔✔Space devoid of matter; light travels fastest.
Oscillation - ✔✔Periodic variation in electric and magnetic fields.
Crest - ✔✔Highest point of a wave.
Trough - ✔✔Lowest point of a wave.
Cycle - ✔✔One complete wave oscillation.
Wave Speed - ✔✔Speed at which wave crests travel.
Inverse Relationship - ✔✔Frequency and wavelength are inversely proportional.
Sound Speed - ✔✔Sound travels at 340 m/s; slower than light.
Delay in Sound - ✔✔Sound takes longer to reach than light.
Light Speed Comparison - ✔✔Light travels nearly a million times faster than sound.
Wavelength - ✔✔Distance between consecutive wave peaks.
Frequency - ✔✔Number of wave cycles per second.
Visible Light - ✔✔Light visible to the human eye.
